What happened to the dab?
Manchester United 1-1 Tottenham
Alan Shearer
Former Newcastle striker on BBC One
That was a brilliant first-half. Spurs were better than United in the first 20 minutes and they got the goal they deserved. Jose Mourinho went absolutely berserk and then United livened up and got back in the game with a bit of quality. Great first 45 minutes.

This was a first-half that flew past in the blink of an eye and it is a perfectly balanced FA Cup semi-final.
Manchester United survived a siege to fight their way back into contention but it ended with dangerous moments from Spurs. The Wembley crowd is living every second of this.
You can now rate the players.
Alexis Sanchez currently leads the way for United, while Christian Eriksen, who has been Spurs' best player is the highest rated player overall.
Agree? Rate them here.
Alexis Sanchez has NOW scored eight goals in his eight appearances at Wembley Stadium for club and country, including four in three FA Cup semi-finals
Manchester United 1-1 Tottenham
The players get a breather, but I think we all need one.
Manchester United 1-1 Tottenham
Eric Dier has a free hit from about 30 yards and his shot ricochets off the post.
Not sure anyone expected that, especially not De Gea who stood still and watched.
Manchester United 1-1 Tottenham
Two minutes of extra-time, what a half this has been.

Danny Murphy

I think Pogba had to take the shot on there. He has got two good feet so it was worth an effort at goal but it didn't really trouble the keeper.
Manchester United 1-1 Tottenham
Alexis Sanchez is putting in a shift here, a player with a point to prove.
He is chasing down everything, winning back lost causes.
Paul Pogba is also playing well and he tries to curl one past Michel Vorm but the Dutchman turns the shot around his far post.
Manchester United 1-1 Tottenham
After a lull in the game, Son Heung-Min accelerates into the box and wins a corner.
But it's poor and David de Gea gathers it easily.
The Spaniard then launches a counter-attack and United are suddenly back in the Spurs box.

Alexis Sanchez's equaliser came from nowhere just as Spurs were threatening to over-run Manchester United and we were hearing the first sounds of frustration from their fans.
Now the mood has changed as United at least look more settled, if not entirely comfortable, in this FA Cup semi-final.
Jose Mourinho will have wanted his big players to make a significant contribution and in a moment Paul Pogba and Sanchez did exactly that.
The mood among United's fans is much better now. This first half has flown by.
Manchester United 1-1 Tottenham
Paul Pogba catches Son Heung-Min and it's another free-kick to Spurs, this time on the right.
It's a mis-hit from Christian Eriksen and United clear.
Manchester United 1-1 Tottenham
Ander Herrera fouls Harry Kane just less than 40 yards from goal.
Within Christian Eriksen's range?
Instead of shooting he sends a low pass towards Kieran Trippier, who clips the ball to the back post but United clear and counter through Romelu Lukaku.

Paul: That's exactly what we need from Pogba - bullying the game and the opposition. And what a top finish from Sanchez.
Lee: Where are all the Pogba and Sanchez haters now?
Jerry: Was typing MUFC playing with 9 players and Pogba and Sanchez, when they combined to conjure that equalizer!
Manchester United 1-1 Tottenham
That goal has settled United down and they are now in the ascendancy.

What can you say about this man Sanchez? He always turns up at Wembley.
A man of his quality was never missing from there. It comes after good strength from Pogba and it's a good header. He gets up early and guides it back across.
Yes he's had a slow start to life at Man United but there's no doubting his quality.
Manchester United 1-1 Tottenham
Another chance for United as Jesse Lingard mistimes a header in the box.
Antonio Valencia has been booked for a challenge on Dele Alli and Son Heung-Min is booked for fouling Sanchez.
Non-stop action at Wembley, it's a corker.
Alexis Sanchez
He loves Wembley.
Two of United's most underfire players combined for the equaliser.
Paul Pogba shrugs off Mousa Dembele on the touchline and crosses for Alexis Sanchez who guides his header past Michel Vorm.
Game on.
This is exactly how Alli put Spurs ahead...
