Once construction is complete, the club’s existing home is likely to be demolished.

Co-owner Sir Jim Ratcliffe said he wanted to build the “world’s greatest football stadium”, which the club hopes could be finished in five years.

United’s announcement comes after an extensive consultation process around whether to develop the existing stadium or build a new one.

Old Trafford has been Manchester United’s home since 1910.

The club would continue to play at Old Trafford until the new stadium was ready.

Senior club sources have previously said it would not be cost effective to shrink it for use as a home for United’s women’s and youth teams.

Architects at Foster and Partners, who will design the project, said the new stadium would feature an umbrella design and a new public plaza that is “twice the size of Trafalgar Square”.

The design will feature three masts described as “the trident”, which the architects say will be 200 metres high and visible from 25 miles away.

Manchester United, currently £1bn in debt, are yet to say how they plan to pay for the stadium. Club chief executive Omar Berrada said it was “a very attractive investment opportunity” and he was “quite confident we’ll find a way to finance the stadium”.

Football finance expert Kieran Maguire said the development can be financed because income from a “multi-functional stadium will more than outweigh the additional interest costs”.

The stadium will form part of a wider regeneration of the Old Trafford area, predicted to be the biggest such project in the United Kingdom since the transformation of the Stratford area that accompanied the 2012 Olympics in London. Chancellor Rachel Reeves has already given government backing to the plans.

United say the entire project has the potential to create 92,000 new jobs, will involve the construction of 17,000 homes and bring an additional 1.8 million visitors to the area annually. They add the project will be worth an additional £7.3bn per year to the UK economy.

“Today marks the start of an incredibly exciting journey to the delivery of what will be the world’s greatest stadium,” said Ratcliffe.

“Our current stadium has served us brilliantly for the past 115 years but it has fallen behind the arenas in world sport.

“I think we may well finish up with the most iconic football stadium in the world.”

He said there was no date in place for when building work on the stadium would begin, adding: “It depends how quickly the Government gets going with the regeneration programme. I think they want to get going quite quickly.”

The stadium will be built using pre-fabrication, shipped in 160 components along the neighbouring Manchester Ship Canal.

Criticism of Old Trafford – England’s biggest club ground with a 74,140 capacity – has grown in recent years, with issues including leaks from the roof of the Sir Bobby Charlton Stand.

The stadium has not had significant development since 2006.

United have spoken to senior people involved in the most recent large-scale stadium developments, including the SoFi Stadium in Los Angeles and the rebuild of Real Madrid’s Bernabeu Stadium, as part of their background work.

They also spoke to local residents and conducted a fan survey to establish whether supporters would prefer a new build or extensive improvements to the present stadium, which was thought likely to cost £1.5bn.

Foster and Partners designed the new Wembley Stadium, which opened in 2007, and the Lusail Stadium, the venue for the 2022 World Cup final in Qatar.

It can be done. Tottenham borrowed a huge sum of money to fund their new stadium, but they have tripled their matchday and commercial income.

It will be a multi-functional stadium and will more than outweigh the additional interest costs.

Part of the payment will have to come through shares or some form of equity payment from Sir Jim Ratcliffe himself.

United successfully dealt with the takeover in 2005 and their interest charges went initially over £100m-a-year and that was when United were a far smaller operation.

My big fear is that some of those costs will be used to put up prices for fans, especially season-ticket holders.

Leaving Old Trafford will be a controversial move for some but former manager Sir Alex Ferguson said: “Manchester United should always strive for the best in everything it does, on and off the pitch, and that includes the stadium we play in.

“Old Trafford holds so many memories for me personally but we must be brave and seize this opportunity to build a new home, fit for the future, where history can be made.”

Greater Manchester mayor Andy Burnham welcomed the plans. He said: “If we get this right, the regeneration impact could be bigger and better than London 2012.

“Manchester United could, and indeed should, have the best football stadium in the world.

“To me, that means a stadium that means a stadium that is true to the traditions of the club, affordable to all, with nobody priced out.”

The Manchester United Supporters Trust (MUST) says it has plenty of questions around the planned stadium.

It wants to know how the club will pay for the ground but says the stadium news “could be very exciting”.

MUST says: “Whilst investment is much-needed and welcome, fans remain anxious about what it means and what the consequences will be.

“Will it drive up ticket prices and force out local fans? Will it harm the atmosphere, which is consistently fans’ top priority in the ground?

“If they are able to produce a new stadium as stunning as the plans suggest without harming the atmosphere and hiking ticket prices this could be very exciting.”

Fan group The 1958, which organised a protest against the club’s ownership on Sunday, added that the design “fails to reflect the club’s deep-rooted heritage, traditions, and connection to its supporters”.

“The design resembles a generic, soulless corporate structure, more akin to a modern entertainment venue than a football cathedral,” the group’s statement added.

“Its circus-like aesthetic disregards the club’s working-class origins and the identity of a fanbase that spans generations.

“Rather than honouring the past and strengthening the bond with the local community, it prioritizes spectacle over substance, alienating those who have defined United’s legacy for decades.”

Barcelona are renovating their Nou Camp home which had a planned capacity of 105,000 when work began. It was already the largest stadium in Europe with a capacity of 99,354.

There are several college stadiums in the United States which hold more than 100,000 people while the Narendra Modi Stadium in Ahmedabad, India, holds up to 132,000.

North Korea has a stadium with a claimed capacity of 150,000 which is often cited as the largest sporting arena in the world. However, the Rungrado 1st of May Stadium is rarely used and a smaller capacity figure is also widely reported.

United played at the largest stadium in the US during a pre-season tour in 2014 where 109,318 saw them beat Real Madrid in Michigan.

1. Narendra Modi Stadium (Ahmedabad, India) – 132,000 capacity, 114,600 seats
2. Rungrado 1st of May Stadium (Pyongyang, North Korea) – 113,281 capacity widely claimed
3. Michigan Stadium (Ann Arbor, Michigan) – 107,601 capacity
4. Beaver Stadium (State College, Pennsylvania) – 107,282
5. Ohio Stadium (Columbus, Ohio) – 102,780
6. Kyle Field (College Station, Texas) – 102,733
7. Tiger Stadium (Baton Rouge, Louisiana) – 102,321
8. Neyland Stadium (Knoxville, Tennessee) – 101,915
9. Darrell K Royal Memorial (Austin, Texas) – 100,119
10. Bryant-Denny Stadium (Tuscaloosa, Alabama) – 100,077

Twenty years, 426 appearances, 138 goals and five trophies later, Marcus Rashford is set to leave for Aston Villa.

It will seem strange to see Rashford – the boy from Wythenshawe, United through and through – wearing another team’s strip.

As recently as November, the idea seemed fanciful.

How did we get here?

Even towards the back end of last week, there was still hopeful talk of a resolution on Rashford’s part. Now the reality is sinking in. Amorim has got his way.

What has been very difficult to pinpoint, even though Amorim has given some frank interviews, is the detailed reasoning why the coach was so willing to let him leave.

It was all sparked when Amorim dropped Rashford for the Manchester derby on 15 December.

Three days earlier, the forward had been substituted 11 minutes into the second half of what looked like being an embarrassing Europa League defeat by Czech side Viktoria Plzen.

Rasmus Hojlund came on to replace him and scored two goals to turn the match into a 2-1 win.

Rashford his been omitted from 11 of 12 squads since.

The one time he did make a squad – the 2-0 home Premier League defeat by Newcastle on 30 December – he was left on the bench. Afterwards, Amorim was asked why.

When he had to address the subject again before Thursday’s Europa League win over Romanian side FCSB, Amorim seemed as if he was starting to get irritated.

There is no doubt he has used the Rashford situation as a test of his strength. Sir Alex Ferguson, an illustrious predecessor, may well have approved.

“If the coach has no control, he will not last,” Ferguson explained in a case study for Harvard Business School, published in the weeks after his retirement in 2013.

“You have to achieve a position of comprehensive control. Players must recognise that as the manager, you have the status to control events. Before I came to United, I told myself I wasn’t going to allow anyone to be stronger than I was. Your personality has to be bigger than theirs.”

Amorim’s latest comments on the Rashford saga were not as polished but the sentiment was the same.

“You [the media] want to make it personal,” said Amorim. “I have nothing against Marcus but I have to make the same rules for everybody.”

It was more or less the same message Amorim delivered at the Etihad Stadium in dropping Rashford and forward Alejandro Garnacho for the Manchester derby win over City.

In various forms, it has been repeated at least half a dozen times in the interim.

“It’s important, the performance in training, the performance in the games, the way you dress, the way you eat, the way you engage with your team-mates, the way you push your team-mates, everything is important in the context of beginning something, when we want to change a lot of things,” Amorim outlined.

“It’s the small details. When people in our club are losing their jobs, we have to put the standards really high.”

Rashford responded to that forceful assertion by using a visit to his old school to tell football writer Henry Winter he was ready for “a new challenge”.

That was widely interpreted to mean the player wanted to leave. But sources close to Rashford explained that, as they understood it, he was voicing a general feeling of frustration rather than a desire to try something new.

They say he felt he was being eased out of a club he remained attached to – a club he felt he knew far better than those running it.

Club sources say Rashford has trained well. Unlike Jadon Sancho, who fell out with former United boss Erik ten Hag, again over standards, Rashford was not banished to a different area of the Carrington training ground and told to change on his own.

While Rashford’s body language has not always presented the most positive image, recent open training showed a different side.

During the 15 minutes session broadcast before the Europa League matches against Rangers and FCSB, Rashford was expressive and light-hearted.

When Amorim ‘ran the gauntlet’ through the first-team squad to mark his 40th birthday, Rashford was among those in the line, smiling after the United boss had charged through.

It has never been plain sailing for Rashford at United.

A succession of managers have felt at times that they were not getting the most out of a player with blinding speed, excellent balance and an eye for goal.

For the 2022-23 season, the first under Ten Hag, Rashford was diligent, going to the United States for personal sessions to ensure he was ready to go when the real preparations began.

The reward was a career-high 30 goals. It is a strike rate no-one else in the United squad can match and is the chief reason why representatives spent time visiting some of European football’s biggest clubs – Barcelona, AC Milan, Borussia Dortmund – gauging interest and trying to work out what kind of a deal was possible before the transfer window closed.

But was the goals output confirmation of Rashford’s talent or the exception amid more mediocre returns in recent times?

The season before, he found the net twice in his final 28 appearances. Since August 2023, he has scored 15 in total. The drop off is alarming. Even sources close to the 27-year-old accept he is not playing well.

However, despite missing the past 11 games, he is still United’s joint-fourth highest scorer this season with seven, the same as £72m signing Hojlund, who has played four more games.

Only Amad Diallo (six), Bruno Fernandes (five) and Hojlund (four) have scored more goals under Amorim than Rashford (three), who has only been on the pitch in 35% of the new head coach’s games at United.

United’s record goalscorer Wayne Rooney has told Rashford in private he should leave. It is an observation he offered to a wider audience on The Overlap podcast.

“I’ve spoken to Marcus a couple of times,” he said. “I’ve given him my thoughts. I’ve said: You need to leave the football club.

“I went into Carrington to take my kids to game day and Marcus was out on the training pitch with the fitness coach, right over towards where the parents were walking past for the kids’ games. I remember looking at him thinking: How embarrassing is it that the parents are walking past?”

Rooney’s former United team-mate Rio Ferdinand used similar terms to describe how he would feel if a manager had called out his training performances as Amorim had to Rashford.

“My heart, my pride, my ego. It’s embarrassment,” Ferdinand said.

“For someone to question you giving 100% for the team, saying you’re lacking effort and taking shortcuts: That’s a damning comment. There’s no way back for Marcus after that.”

One theory floated by a source with an understanding of the workings at Old Trafford pointed to financial matters.

Rashford and Casemiro – who has not been omitted from Amorim’s squad like the England man but has played only three times since the Plzen game – are by far United’s highest earners. The theory is their presence makes it difficult for United to get their profligacy in the transfer market under control.

If they left, representatives of prospective signings would be unable to use them as a benchmark for wage negotiations.

Consequently, it is not until those salaries are off the books that United can properly start to move forward in a more sustainable manner, without the threat of profit and sustainability breaches hanging over them. Those rules also feed the view that homegrown stars such as Alejandro Garnacho and Kobbie Mainoo might need to be sold.

United have grown used to subsidising moves for highly paid players who not reaching the standards required and no longer wanted by the manager of the day. Their wage bill is one of the highest in world football. Few would say United have been getting value for money.

Alexis Sanchez, Donny van de Beek, Romelu Lukaku, Anthony Martial and Sancho have all fallen into that bracket.

Rashford is the next one out, with United believing they have done well to negotiate a deal that, they say, covers 75% of his wages.

Sources close to the player were adamant the interest in him was huge.

There were offers from the Saudi Pro-League, but he felt accepting might mean abandoning his England career.

A big ambition was to join Barcelona, but they needed to offload players to make it happen. That scenario never materialised into anything close to reality.

So Villa, emboldened financially by the £71m sale of Jhon Duran to Al-Nassr, made their pitch.

There is plenty about the switch that makes sense. Villa’s status is currently greater than that of United. They are pushing for a top-five slot, despite Saturday’s defeat at Wolves, and have a Champions League last-16 game in March to look forward to. Unai Emery needs someone who can play through the centre, if required, or in a wide slot. Although he prefers to be on the left, Rashford can do all of this.

Emery, it is being stressed, was a huge selling point. On a personal level, Rashford doesn’t need to move house.

So the lifelong Manchester United fan, who felt so entwined with his team, will now wear the claret and blue of Villa, at least until the end of the season.

As for Amorim, he has made the big call. He no longer has to answer questions about a player who belongs to another club.

But he needs to deliver success himself. If he doesn’t, and Rashford does well, he will be in a very uncomfortable position.
