Drama and magic of the FA Cup aside...surely the games gone if referees are giving penalties for handball when the ball is hitting the upper arm in a natural position from point blank.

United are so, so close to taking the lead as Bruno Fernandes fires an absolute rocket of a shot off the crossbar from the edge of the box from Amad Diallo's cutback.

This is why this is the best cup in the world.
Coventry 3-3 Man Utd
Not much energy to this extra time so far. It doesn't feel like Erik ten Hag has fired the United players up before sending them out based on this.
Coventry 3-3 Man Utd
Not a day for the keepers, this. Both sides have only had four shots on target.

I can't believe what I'm watching. You're looking for leadership but it isn't there.
The momentum is with Coventry but if Man Utd don't get over the line then... oh I don't know what to say.
Coventry 3-3 Man Utd
United get extra time going. Their players surely cannot believe they're here.
FT: Coventry 3-3 Man Utd
I definitely thought I'd be writing things like "Erik ten Hag congratulates his players on the pitch, we have an all-Manchester FA Cup final" by now.

I thought I would be saying goodbye and leaving the stadium.
It is ridiculous, what a game of football we have seen - it was a boring affair in the first half!
Anything can happen.

United are terrible so throwing away three nil leads is not exactly a surprise but refs are the stars of football now in their own minds, they decide the games not the players.

Wonder which post Garnacho is going to like tonight. No matter how he plays, he has become a talisman for Man Utd. His substitutions are leading to the team switching off. All credit to Coventry for capitalising!

Absolute incompetence. Shambles. 3-0 up against a team in a league below you. What's the plan? I bet a lot of money there isn't one right now.

The FA Cup has been going since 1871. How many FA Cup semi-finals in 153 years will have been that dramatic?

We're going to extra time after one of the most remarkable FA Cup semi-finals in history.

We're past the 100-minute mark.

'You're getting sacked in the morning, sacked in the morning'.
Coventry fans are taunting Erik ten Hag.
Coventry 3-3 Man Utd
Almost a chance for United to win it! Good run by Amad Diallo but Bradley Collins blocks Bruno Fernandes' cross.

United keeper Andre Onana races out of his box to stop Ellis Simms getting onto a long ball for a one on one.

Marcus Rashford pulls up while making a run and he has to be replaced by Amad Diallo, United's quarter-final hero.

Coventry went 3-0 down and we think it is over!
Credit to Haji Wright he sent Andre Onana the wrong way!
