Into the last five minutes. Arsenal so close to a 20th final. 

Adam: Aguero would have buried that Delph chance all day. Should have passed to Sané anyways

Danny Welbeck leads a one-man break down the left wing but he can't find a team-mate at the end of it, before Kevin de Bruyne flashes a cross/shot right across the face of goal and a few feet wide.

Nicolas Otamendi is then booked. 

Will Manchester City get a better chance than that? They are having nearly all of the ball once more as Kelechi Iheanacho squirts a header wide under heavy pressure, Kevin de Bruyne is then crowded out on the edge of the area.

It's a fantastic break with lots of pace. It comes to Delph. We're just waiting for the ball to hit the net. It comes off Bellerin, and it's an outstanding block.

That was a great chance. Kevin de Bruyne maybe should have hit that earlier but the pass was on.

It is a very good block from Bellerin in the end. I am surprised De Bruyne passed it.

There are only so many of those chances you can let pass by.

Ten minutes left. Can City find a goal? Here they come on the break, Kevin de Bruyne tees up Fabian Delph, arriving at pace - wide!

It looks like a bad miss but credit Hector Bellerin, he made a vital block to turn it into the side-netting.

Manchester City free-kick in a good spot, Yaya Toure lines it up but thumps a shot into the wall. Cleared. 

Sanchez gives the Gunners the lead. Can they hold off City to win the semi?

Fabian Delph has the first shot of extra-time II, but can only scuff a shot wide. It was from the same spot as Nemanja Matic's screamer yesterday, but that's where the similarities end.

Kelechi Iheanacho is then almost in, fresh and fast, but he treads on the ball. Free-kick though...

Kelechi Iheanacho has not featured much in the second half of this season but he can really sniff a goal out, he was the obvious man for this particular job. 

Kelechi Iheanacho replaces Raheem Sterling, himself a substitute, as Manchester City become the first team to make FOUR substitutes.

Pep Guardiola is gambling here, but he needs a centre-forward. Iheanacho has that pace City need. It's been difficult for them without Aguero on the pitch.

Pep Guardiola is very animated, lots of arm waving and pointing. 

It's finishing like that which separates Danny Welbeck from the very best strikers. It looks like Manchester City are going to bring on Kelechi Iheanacho.

Not only has Welbeck stuck it wide he has took it off the head of Monreal. 

Welbeck was going away from goal, it was always a difficult header.
