Manchester City midfielder Fabian Delph says they players know they can do better after their 3-0 win against Fulham.
Leroy Sane, restored to the starting XI, put City ahead after just 90 seconds before David Silva and Raheem Sterling struck.
Delph played his first minutes of the season in the match and looked fit and sharp at left-back.
He said, "I felt like I won most of my duels and I was communicating well with the rest of the team. I couldn't get my feet sorted at times! But that will come with more match time and fitness.
"It was frustrating to not put more chances into the ball of the net - we need to be more ruthless. We knew Fulham could be a threat - they have been impressive already this season. But we started with the mindset that we needed to be on the front foot. We try to do that in every game."
