Pep Guardiola believes his Manchester City side will improve over the course of the season.
City are currently two points off title rivals Chelsea and Liverpool, who have maintained their 100 per cent record this season.
But Guardiola is confident his side will make up ground after the international break.
"We will improve," he said. "It's almost impossible after the World Cup, after what happened last season, mentally for the players and everybody to be in the best condition.
"We need more time and after the international break the season starts properly in terms of having games every three days.
"What we have to do is what we have to do – try to be better than the opponent every single game, try to follow what we spoke about and prepared.
"This period, in the five official games we've played, it's happened. We would like to score more goals but we created the chances."
