Manchester City defender Joleon Lescott is confident going into their clash with Manchester United despite their Champions League flop.
Lescott has dismissed fears City's European woes will hinder their league form, insisting they will be ready for the visit of their city rivals.
"We haven't done that great in the Champions League so far this season but it hasn't affected our Premier League form so there is no reason to suggest it should this weekend," said the former Everton and Wolves defender.
"We know it's a derby, it's a massive game and the chance to stay unbeaten and go top of the league."
