Mancini admits his team are yet to find the form they showed last season but believes they are moving in the right direction.
"I was worried because we continued to play well and had chances," Mancini said. "We didn't score for 87 minutes and I am very pleased for Edin because he scored an important goal.
"It is also difficult for me to choose 11 players because I have 17, 18, 20 players that are really good.
"We play every three days so we need all of these players. Fulham is a difficult pitch so it was really important to have all these good players.
"I think that we were very close to the same we played last year.
"The problem we had was we didn't have all the players in pre-season. Twelve players started their pre-season 10 days before the championship began, which is difficult.
"I think, in my opinion, maybe after the international break we will be OK."
