Dzeko struck in the 14th minute at the Etihad Stadium, meeting David Silva's cut-back with a low shot that bobbled over the line despite Kevin McNaughton's attempted last-ditch clearance.

Manuel Pellegrini's side have been in free-scoring form this season, putting six goals past Arsenal and Tottenham Hotspur, outclassing Manchester United 4-1, and crushing Norwich City 7-0.

With 59 goals from 21 games, prior to kick-off, City are on track to surpass the Premier League goal-scoring record set by Carlo Ancelotti's Chelsea, who scored 103 goals en route to the title in 2009-10.
