Helpless as the defence in front of him collapsed under City's pressure. Had no chance with Balotelli's brace.
Looked all at sea on his unaccustomed right-back berth. Failed to track Balotelli for the striker's first. Gamble didn't pay off for Di Matteo.
Clueless in the face of Silva's guile. Di Matteo would have seen all the evidence he needed to justify his usual position in the wilderness. Removed for Barnes as Baggies went for the jugular.
Played support role in helpless centre-back pairing. On this form, plain to see why Atletico Madrid let the ex-Spain international's contract run down in the summer. Booked.
Flopped after a series of storming performance. Given second yellow card after lunge on Tevez. Previously, had made meal of swipe from Balotelli to get him sent-off.
No chemistry with Shorey as the pair were positioned on their unusual right flank. Almost got Baggies off to perfect start when Kolo Toure was sharp to steal the ball from him in the third minute. Booked.
Axis with Mulumbu in central midfield fell apart. Offered no cover for defence as Yaya Toure drove on impeded from the centre. Taken off for Miller.
Match passed the centre forward by. Had as many touches today as he did against Blackpool before he was withdrawn in the wake of Ibanez's early red card.
Ran the channels and offered plenty of energy. Forays forward were supported inadequately by his colleagues. Made way for returning hero Odemwingie.
Left to freeze on a cold afternoon as so rarely called into action. Asserted dominance in early minutes with a firm punch from a corner.
Defensively suspect as always but a danger going forward. Almost finished off brilliant Silva pass in second half.
Huge presence at the back ensured clean sheet despite playing among 10 men. Always first to every loose ball and header.
Alert at beginning to steal ball from Brunt's toes. Never troubled by Baggies' strike pairing.
Continued recent up turn in form with a strong display at full-back. Fizzed one effort just over the bar in first half. Substituted for Kolarov. Booked.
N. de Jong
Set platform for Blues' dominance in middle. Bullied Scharner and Mulumbu. Helped double up on dangerous Thomas. Booked.
On a different level to his hapless opponents. Pulled the strings unopposed as he drifted from out wide to the middle. Began move for Balotelli's first and set up second with long pass. Taken off for Johnson.
Great end-to-end performance from the Ivorian powerhouse. Left Scharner in his dust. Played one delicate pass to set up Silva.
Quietly got about business of winning the ball in middle of the pitch. On end of tough, but fair, tackle from Thomas. Booked.
Welcome return after week in Argentina. Pulled centre-backs apart and set up Balotelli's opener. On receiving end of vicious tackle from Mulumbu for midfielder's second caution.
Stole the headlines once again after double then sending off. Took both goals clinically, with second strike hammered past Carson. Wild side on show after needless swipe on Mulumbu, which earned straight red card.

Former City starlet was brought on as battering ram in 80th minute. Given no service to strike against former employers.
Made return from knee injury in 60th minute. Starved off chance to kick back into gear.
Added to Baggies attack on the hour mark. Showed skill in rare moments involved.
