Italian is frustrated that injuries have deprived him of central midfield options to supplement Yaya Toure and Gareth Barry, and hopes his side are more clinical in future
"We are lacking at this moment because we lost two midfielders,” the City boss told reporters. “I don't have players at the moment. I can only change the full-backs.
City dominated for well over an hour at Craven Cottage and found itself two goals up thanks to a brace from Sergio Aguero, but goals from Bobby Zamora and Danny Murphy completed a stirring comeback for the home side.
The result put an end to City’s 100 percent start to the Premier League season and also saw it lose ground on rivals Manchester United in the title race, after Sir Alex Ferguson’s men saw off Chelsea at Old Trafford on Sunday.
After the match, Mancini revealed he believes that injuries to several key midfielders have taken their toll.
"I have only two midfielders, because James [Milner] and [Nigel] De Jong have injuries."
While he was pleased with the way his side took control of Sunday’s match, Mancini considers the result to be a warning that City must be more clinical if they are to challenge for the title.
"What team comes here against Fulham in London and has over 70% of ball possession," he asked.
He added, "We had the same problem against Wigan at home. We had 15 chances in the first half and we scored only one goal. It doesn't always go well if you don't score, if you don't close the game."
