Suffered a bit in the slick conditions, mishandling a low cross early on.
Dominated aerially and won plenty of balls off the toes of Chelsea attackers. Started the move for Nasri's goal. Booked for a heavy hit on Eden Hazard.
Tidied up possession efficiently and didn't suffer as much torment at the hands of Hazard as he did in the recent league game.
A satisfying if occasionally creaky display from the lesser-spotted England international, who had a goal chalked off for offside and defended gamely in the closing stages.
Made good use of the ball on the left flank in an attacking sense, starting the move which led to the City opener.
Put in some tantalising crosses from the right, including one which Edin Dzeko should have put away.
Played like he had a point to prove against Nemanja Matic, with aggression characterising his game.
Roved from his nominal left-wing station to agitate the Chelsea back four and had a key hand in Jovetic's goal as well as providing the assist for Nasri.
Kept his discipline and the team's shape in the heart of the midfield, rarely wasting possession.
Combined well with Jovetic, playing the Montenegrin in beautifully for the first-half goal. Had a few chances of his own too. Looked sharper than in recent outings.
Left the field midway through the second half to a rousing ovation after an effective display. Lively and scored a fine goal.
Helpless during both goals but was jittery at times with his handling and kicking.
Thankless task defending alongside David Luiz but popped up nonetheless with some blocks and interceptions.
Was given a tricky time by the City combination play, involving David Silva and Pablo Zabaleta in particular, and could have defended better during the opener.
Left with freedom to roam the right flank as David Silva pushed inside and created some trouble in the first half.
Lost both Silva and Samir Nasri in the build-up to the second goal in what was a real horror show. Was booked, positioned himself bizarrely at times and is, quite simply, ill-suited to Mourinho's back four.
Not nearly as influential as he was in the recent league game in what was a disappointing outing. No consistency to his play on the night.
Fielded on the right and the centre in a vain attempt to influence proceedings but the best he managed was a shot well over the bar.

Did not have the pace to stay with Nasri for the second goal and was generally second to most things in midfield.
Could not find the space he needed to truly affect the game and only flickered as an attacking threat with his neat footwork.
Came off second-best to Yaya Toure and Javi Garcia in the midfield battle, as evidenced by a frustrated hack at the Ivorian in the closing stages.
Battled for scraps and was hauled off after an anonymous 45 minutes.
