Manchester United’s valuation on the New York Stock Exchange plummeted by more than £500million in the wake of a report that the Glazers have decided not to sell.

Nine months ago the owners announced a full sale was among the options being considered as part of a strategic review at the Old Trafford club.

Sheikh Jassim and Sir Jim Ratcliffe made offers to buy United, yet the interminable potential takeover process rumbles on as fans continue to protest against the Glazers.

Hopes of a full sale were seemingly dashed when the Mail on Sunday reported that the owners are taking the club off the market and will try to sell again in 2025.

That report led to more than £500m being knocked off United’s share price on Tuesday.

After the New York Stock Exchange reopened following the Labor Day holiday, the price plummeted from 23.66 US dollars (£18.83) to 19.35 US dollars (£15.40) by close.

United’s market capitalisation – the company’s worth on the stock market – was left at 3.15billion US dollars (£2.5billion) after the 18.22 per cent drop.

Earlier this year the Glazer family reportedly valued United at £6bn.

Manchester United fans protested against the Glazer family before and during Sunday’s Premier League match against Aston Villa.

Friday was the third, and what is expected to be final, deadline for interested parties to make offers to buy the club.

Sheikh Jassim and Sir Jim Ratcliffe both submitted offers to the Glazers, who have faced fury from United fans since their leveraged takeover in 2005.

The 1958 – a United fan group that came to prominence last year – has led renewed protests and held another before the home match against Villa.

Leaving from central Manchester, the march continued on to Old Trafford as fans displayed a giant banner reading ‘Full $ale Only’.

Smoke from the flares outside rose through the concourses and filled the air inside Old Trafford as the players warmed up.

The 1958 also called for an 18-minute boycott of the match – “one minute for each year the Glazers have driven our club into the ground”. There were some visible empty seats at kick-off but Old Trafford was largely full.

Chants against the owners were heard from the outset and footage has emerged of manager Erik ten Hag briefly holding a green and gold scarf after Sunday’s 1-0 win.

Asked if background anger could make things harder for his side, the United boss said: “We felt really that the fans were behind us.

“So, we have to focus to be successful because that’s what the fans expect and they can expect.

“They have to rely on us, so we will focus on that.

“I’m sure when we keep performances like we do all season, the fans are behind us and there’s lot of energy and I think a really strong bond between the fans and the players.”
