Manchester City boss Roberto Mancini admits their clash with Manchester United later this season is likely to be a title decider.
Mancini accepts there is little room for error and that the meeting of the two Manchester clubs in April could well prove decisive.
Mancini does not want any slip-ups against relegation-threatened Bolton Wanderers.
He said: "I think it will be the same game we played against Blackburn, very difficult.
"If you don't score you can have a problem - Bolton play football.
"All these games are tough because they play for relegation and they fight for every ball."He said: "Probably - it could be. I don't know what will happen in these nine games before United, but I think United will win 11 games from now until the end. We need to do the same."
