Dzeko’s goal suggested they still have the same never-say-die spirit that won it for them when Agüero scored his late winner against Queens Park Rangers on the final day of the season. But their defence, and captain Vincent Kompany, are not what they were. When Mladen Petric scored for Fulham from the penalty spot in the tenth minute, City become the first Premier League champions to concede goals in each of their opening six games, and they have failed to keep a clean sheet in three other matches.
