Vincent Kompany has said Manchester City are not worried by their inability to keep a clean sheet so far this season and insists their best is still to come.
The Premier League champions have conceded seven goals in four games, including the Community Shield, and have endured defensive difficulties.
City had the division's best defensive record last season but have already conceded five more goals than Arsenal and, after only letting in 12 at home in their title-winning campaign, have seen Southampton score twice and QPR once at the Etihad Stadium.
But the Belgian believes City will secure shutouts in tougher circumstances.
"It doesn't matter," he said. "We've always proved to be solid come difficult times. "Come December, January and February we'll show it. At this time everyone tries to play the game nicely. We left ourselves exposed but at the end of the season we won't do that."
The City captain says his side can play better but believes that taking seven points from a possible nine is a fine start to the season.
"What's missing? Two points out of nine, that's all," Kompany added. "I'm leaving for the internationals now and if I had to leave one message for the team it would be, 'Well done guys, we've battled hard, we've shown how strong we are'.
"If we are able to get results playing what people say might not be our best, then what will happen when we do? The best is yet to come."
