Wigan 0 Manchester City 1: Dzeko heads City clear at the top
Edin Dzeko ended an 11-match scoring drought to give Barclays Premier League leaders Manchester City all three points at basement boys Wigan.
The Bosnian leapt highest to steer David Silva's 21st-minute free-kick past Ali Al Habsi.
It was Dzeko's 14th goal of the season but his first since the beginning of November for a City side who spent most of the half on top despite being without five key men.

Referee: Martin Atkinson
City applied some pressure in the opening few seconds, although it was Wigan who had the first flurry of opportunities, the last of which, from James McArthur, struck James Milner and rolled out for a corner.
James McCarthy robbed Silva with a thunderous challenge, but City should have gone in front when Gael Clichy curled over a cross from the left which Edin Dzeko turned wide when he might well have found the net.
Samir Nasri almost got a sight of the Wigan goal, but Ronnie Stam nipped in to rob him.
Dzeko got his head to the corner, but Hugo Rodallega cleared, then Stefan Savic nodded over as City continued their forward momentum.
Rodallega led a Wigan counter that ended with Moses blazing over as his better-placed team-mate screamed for a return pass.
Silva had two shots from the edge of the area blocked, then Ali Al Habsi made a feet-first save to deny Sergio Aguero, although the South American was offside anyway.

The face says it all: Dzeko shows his joy after scoring
McArthur and Pablo Zabaleta both went in with feet raised, although it was City who got the free-kick, which ended in disappointing fashion when Milner drilled a crossfield pass straight out of play.
Having lasted so long, Wigan boss Roberto Martinez would have been disappointed in the manner which City went in front.
Antolin Alcaraz brought Dzeko down and, direct from Silva's free-kick, the Bosnian leapt highest and found the bottom corner with a precise header.
Nasri led another forward charge for the visitors and Albert Crusat needed to make a well-timed intervention to deny Zabaleta.

Stam endured the derision of the City fans when he ballooned an attempted cross straight into the stand behind the goal.
A quickly-taken Moses throw led to a half-chance for McArthur, but Joe Hart was able to gather his 20-yard effort at the second attempt.
Gareth Barry scooped a shot over from Silva's lay-off as play quickly shifted to the other end.
Some awful Wigan defending inside their own penalty area led to a chance for Silva, which was blocked.
Going close: Sergio Aguero misses a chance for City
Far too often, the hosts' attempt to pass their way towards the City goal led to them losing ground and then possession anyway.
Under the circumstances, calls for a more direct approach were understandable as were the jeers when a long free-kick floated straight through to Hart.
A decent Wigan attack came to nothing as Moses attempted to check back once too often, then Al Habsi produced a fine one-handed save to deny Aguero two minutes before the break.
Wigan started the second-half with vigour.
In a muddle: Jordi Gomez tangles with Gareth Barry
Barry needed to slide in on Crusat to prevent the winger getting a clear sight of goal, then Clichy headed clear as Rodallega waited to pounce on any mistake.
Stam won a corner off Clichy but Jordi Gomez took it short, Wigan lost possession and City cleared their lines.
That City were still not entirely comfortable with themselves was shown in a complete mis-kick by Barry, Wigan eventually firing wide through McArthur.
Al Habsi produced a brilliant double save, first to deny Dzeko, whose curling effort was heading towards the top corner, then, Silva, whose close-range effort was also going in.

Going clear: Roberto Mancini saw his side regain their three point advantage at the top of the table
Then, after he had weaved his way past three Wigan defenders to get himself a clear sight of the Wigan goal from only six yards, Aguero had the ball taken off his toes by Dzeko, whose shot was too weak to trouble Al Habsi.
After McArthur had been booked for pulling back Dzeko, Caldwell was fortunate that he didn't turn Clichy's cross into his own net as the ball seemed to get tangled in between his legs before running behind for a corner.
Midway through the half, not long after Caldwell had got perilously close to handling the ball as he went for a header, Franco di Santo and Ben Watson replaced Crusat and McArthur.
Wigan came close to levelling when Rodallega rolled a pass to McCarthy, who forced Hart into an excellent save with his legs.
Nigel de Jong replaced Nasri 17 minutes from time, then Hart made a save he did not need to as he turned McCarthy's shot round for a corner.
Zabaleta, McCarthy and De Jong were all booked in quick succession before Nedum Onuoha replaced Nasri.
Al Habsi then produced a fine save to deny Dzeko before Aguero fired wide after finding himself in space on the edge of the area.
After recent controversies, Mancini was left fuming two minutes from time when referee Martin Atkinson failed to send off Maynor Figueroa for a deliberate handball when he deliberately stopped a De Jong through-ball that would have sent Aguero clean though.
