As the afternoon train arrived in London Euston from Manchester Piccadilly, hundreds of Reds descended onto the capital, forcing the locals to hear them coming.

"Erik ten Hag's red and white army" and "We're the famous Man United and we're going to Wembley" echoed around Euston Station as fans streamed into the underground.

On the journey down, a fan was overheard saying: "If we don't win the FA Cup then I think Ten Hag has to go." United progressed to the final of England's oldest cup competition against Coventry but Manchester City will kill them on May 25 if they perform as they did again.

United were 3-0 up on 70 minutes, seemingly cruising to a repeat of last season's FA Cup final, and they spectacularly collapsed against an eighth-placed Championship side.

Coventry, who showed United far too much respect in the first half, offered nothing for most of the game, but they smelt an opportunity after Ellis Simms' well-taken goal and would have completed one of the finest comebacks in FA Cup history if VAR hadn't existed.

There was a great line in Mark Robins' post-match press conference when the Coventry manager said penalties wouldn't have been needed if Haji Wright had cut his toenails.

Wright provided the assist for Victor Torp's goal to make it 4-3 in the last minute of extra-time and VAR revealed him to have been offside by the barest of margins.

Watching Ten Hag as Coventry celebrated was fascinating. He stood motionless with hands in his pockets for longer than 20 seconds and the players sunk into the turf.

Ten Hag was staring down the barrel of a gun and his stay of execution was extended by VAR, but he's a dead man walking and a change in the summer seems inevitable.

Although Sir Jim Ratcliffe was in attendance at Wembley after, remarkably, completing the London Marathon at 71 years old, watching United was probably more exhausting.

The camera picked up Ratcliffe covering his face with his hands when Coventry made it 3-2 and it's likely he had a lower resting heartbeat during his 26-mile slog.

When Rasmus Hojlund scored the winning penalty, Antony looked to provoke Coventry's players by cupping his ears while Harry Maguire shook hands with each in sky blue.

United scraped through and it was embarrassing to see Antony celebrate in that manner, and it also showed the gulf in class between the winger and Maguire.

After moving closer to the brink, Ten Hag sounded delusional in his press conference and insisted United shouldn't be embarrassed with their performance. His card is marked regardless, but he would have received more respect from supporters for saying it how it was.

Before the game, the MEN spoke to fans about Ten Hag's future on Wembley Way and each responded with sensible, well-thought-out opinions about the debate.

Sam said: "I think it hangs in the balance at the moment. The league form has fallen off a cliff, so I think he needs this if he's going to have hope of staying on next year.

"He's had a lot to contend with, but when you look at things like the -1 goal difference in the league it's not good enough. There's a little bit of grace with him after the arrival of the new structure, but I think it's 50/50 and if he doesn't win the FA Cup, I don't think he'll be here.

"It's tough, I want to support him, but the last few weeks have made it harder and harder to defend him. That Brentford game away from home was difficult to watch."

Spencer said: "I'd keep him for another season. His contract is up next year and there's nobody out there right now to replace him, so I'd see what INEOS are doing with the board. I'd give him time with that new structure in place, with a proper recruitment strategy."

Seven fans were interviewed and although each expressed concerns about Ten Hag, none of those supporters outright said they wanted him to be sacked.

That might have changed when they left Wembley. The performance felt like it represented the point of no return for Ten Hag and a group of fans openly discussed options to replace him on the train back to Manchester, with Thomas Tuchel appearing a popular choice.

The writing is on the wall for Ten Hag - his days as United manager are numbered.
