Manchester City boss Roberto Mancini says he's at fault for their defeat to Everton.

Former Manchester United midfielder Darron Gibson, whose old club now trail the leaders only on goal difference, scored the only goal of the game on the hour.

Mancini said: "I didn't prepare well for this game. I thought it was maybe easier. I know here it is never easy, never.

"I acknowledge my mistake. It is important for me to know this because, like this, I can't do the same mistakes in the next game."

When asked to elaborate on his mistakes in his post-match press conference, Mancini referred to the team's training in recent days.

He said: "The players put everything on the pitch but I made some mistakes during the last three days preparing for this game.

"I didn't prepare very well. For this reason we lost this game but I also feel we didn't deserve it because they had two chances to score and we were so unlucky in the same situation."
