Arjun Singh: I’m actually glad Mount gets a rest. The lad’s played every game in a 3-game-a-week schedule for the last three months! Just a shame Kovacic picked up his injury.

Chelsea are under a lot of pressure now. The two players who have come on for City have had an immediate impact.
City are getting balls into the box and looking far more dangerous.

You can see the difference Gudogan has made on the right side, linking with Cancelo. Foden is getting in the box.
Ruben Dias, with the quality he has... he's just got to get the feintest of touches but he gets it all wrong.

Mark Burt: Some matches are like burger and fries, no frills and fast. This is like a five-course taster menu. Slow, small portions of excitement but extremely satisfying in its own way.

Chelsea attempt another ball down the middle for Hakim Ziyech to chase but Zack Steffen once again comes off his line to deal with the danger. Manchester City then attack but Raheem Sterling runs into trouble in the shape of Jorginho as he tries to break into the box.

City have nothing going on. There’s no threat. They haven’t really got anything that’s going to worry that back line of Chelsea.

Aleks Yakubssohn: It has 3-0 Chelsea written all over it. I don't see where Pep is gonna pull his magic trump card from now. In this game they haven't even woken up yet.

As a centre-back you have to be in the right position. Ruben Dias never looked like he was going to get there.
He tried to put a challenge in at the end, but there was no point because he was ahead of him. He has to make a decision a little bit quicker.
Chelsea 1-0 Man City
Manchester City are struggling to cope with the pace of the Chelsea attack. Suddenly this tie has burst into life.
Chelsea 1-0 Man City
Oh what a chance for a second!
Ruben Dias fluffs his attempted clearance and Hakim Ziyech is in on goal but Zack Steffen is off his line quickly to close down the gap and block Ziyech's shot.
Good save but Ziyech should have done better and he knows it as he slams the pitch in frustration.

Two hefty blows for Manchester City in quick succession, the loss of the injured De Bruyne then going behind.
Big moments now for both sides.

It was always going to be on a break, from Chelsea’s point of view. The City defenders are asking Zack Steffen why he didn’t come out. That gave Chelsea space to manoeuvre.
Timo Werner has the presence of mind just to lay it in front of Hakim Ziyech. It’s a brilliant break from Chelsea.
