Manchester City boss Pep Guardiola says the fans made a big contribution to their derby win against Manchester United.

City everntually overran United 3-1, having been trailing at halftime.

"What we won in the past, that gives us the confidence that we can do whatever we want," Guardiola said.

"In this kind of game, the only problem you have in losing 1-0 is you lose your composure and lose what you have to do and then you lose 3-0 because United lived for that transition with (Alejandro) Garnacho and Rashford and set-pieces and they were really good.

"We managed it well. The first minute of the second half was not our best but it's normal after half time. Phil scored one goal and our people the second and the third.

"The mood and environment helped us to score the next two."
