Joe Hart 7/10
Unexpected selection, perhaps as Costel Pantilimon said this would be his last City game, so why should Mancini pick him? Stood up well to both McManaman breaks.
Pablo Zabaleta 5/10
Might have conceded a penalty with rash tackle on Espinoza after 30 minutes. Not able to supplement attack as much as usual. Sent off.
Gael Clichy 5/10
The French full-back was given a torrid time by McManaman's tricks and pace, meaning his attacking influence was reduced too.
Vincent Kompany 6/10
Wigan tended to attack down the flanks leaving City's skipper marking space for much of the game.
Matija Nastasic 6/10
Looked composed. However, could have paid dearly when he let McManaman slip away from him after 35 minutes.
Yaya Toure 5/10
Strangely subdued in the first half which meant Wigan were allowed too much time on the ball.
Gareth Barry 5/10
One of three English-qualified starters but did little of note. Booked.
Samir Nasri 6/10
Lively in patches setting up chance for Tevez and testing Robles, so unlucky to pay the price for City's lethargy being subbed before the hour.
David Silva 5/10
Flashed a header wide but quiet by his standards. Set-pieces poor.
Sergio Aguero 6/10
Took up good positions, but lacked service. Made bright run to create a Tevez chance.
carlos tevez 5/10
Denied by good 28th-minte save from Robles, but should have scored. Otherwise made little impact and withdrawn.
Substitutes James Milner for Nasri, 54 minutes; Jack Rodwell for Tevez, 69 minutes.
Joel Robles 8/10
Excellent first-half saves from Toure, Tevez and Nasri fully justifying his inclusion ahead of Al Habsi. Less impressive dealing with crosses.
Emmerson Boyce 7/10
Barbadian international from Aylesbury who was effective on right of Wigan's back three. Made crucial block when Aguero got free.
Paul Scharner 7/10
Austrian was beaten too easily by Tevez once but otherwise solid and composed in defence ad a threat in the air going forward.
Antolin Alcaraz 8/10
Passed late fitness test for which Martinez will be grateful as he marshalled Wigan's usually porous defence with intelligence.
Roger Espinoza 8/10
Eye-catching display and not just because of his flowing locks. Could have had a penalty when tripped by Zabaleta.
James McArthur 7/10
Given an unfamiliar wing-back role he was assiduous in blocking City's attacks while also supporting McManaman.
Jordi Gomez 7/10
Tidy but unable to make the spectacular impact he did in the quarter-final at Goodison Park.
Shaun Maloney 6/10
Hit the bar with a 75th-minute free-kick but Hart unworried. The Scot was not as influential as he usually has been this season.
James McCarthy 8/10
Composed on the ball, used possession well, he showed why so many clubs are tracking his progress.
Callum McManaman 9/10
Highly impressive performance form the youngster giving Clichy a nightmare and prompting Zabaleta dismissal. Only flaw was inability to take chances.
Arouna Kone 7/10
Lively and always a concern to City's defence. Positional discipline excellent but not always took the right decision in possession.
