Chelsea 0-2 Man City
Another chance for Brahim Díaz but Caballero makes a fine save. Chelsea could have been seriously embarrassed but for the Argentine's saves.

Huge roar as Sergio Aguero is named man of the match. Can't argue with that decision.
Chelsea 0-2 Man City
Four additional minutes. There's not too many Chelsea fans left inside Wembley.

Its a very good, professional performance from a City side that are only going to get better.
Chelsea 0-2 Man City
Pinball inside City's penalty area. Claudio Bravo just about does enough to deny Tammy Abraham a consolation. Bravo is clattered in the process but he's OK to continue.
Chelsea 0-2 Man City
Will Nicolas Otamendi get a touch? Late, late change by City. Laporte makes way.
Chelsea 0-2 Man City
Chelsea's players look cheesed off. The full-time whistle can't come soon enough. City, in contrast, are hungry for another goal. There's still time.
Chelsea 0-2 Man City
Agonising for Aguero as he is denied a Wembley hat-trick.
Chelsea 0-2 Man City
Confidence is not something Brahim Díaz lacks. The teenager is running circles around Chelsea's defence and Willy Caballero is forced into a smart save by the substitute. Chelsea's keeper then denies Gabriel Jesus.
Wave after wave of City attacks...
Chelsea 0-2 Man City
More changes.
Chelsea replace Pedro with Victor Moses while Sergio Aguero's hopes of a hat-trick disappear as he makes way for Vincent Kompany.

Chelsea are looking a little bit leggy, they're persevering but they just can't seem to get the ball back at the moment.
It hasn't gone Chelsea's way at all.
Chelsea 0-2 Man City
A shuffle from Brahim Díaz leaves Marcos Alonso trailing and the City substitute is in on goal. Side-netting!

Am I the only one who thinks a world class defender/sweeper needs to be signed? Our defence is being easily split open by simple passes!

Phil Foden has been excellent. He is a very comfortable technician on the ball.
Chelsea 0-2 Man City
And the changes keep on coming.
Phil Foden is replaced by fellow teenager Brahim Díaz.
Foden has been terrific. We're going to see him in City's first team much more this season.

Sergio Aguero is finding those pockets of space. He's staying out of the way, out of sight and the Chelsea defenders just don't know where he is or who to mark.
Chelsea 0-2 Man City
Wembley hat-tricks don't come along often and Sergio Aguero is holding his head in his hands as Willy Caballero keeps out his close range attempt.
Great chance. Decent save.
Chelsea 0-2 Man City
Tammy Abraham has been sent on to nick his side a goal. Alvaro Morata makes way. Another game without a goal for the Spaniard.
Chelsea 0-2 Man City
Belting start to the campaign for Sergio Aguero...

Hands up if you're going to be busy in the transfer window this week...
