Roberto Mancini: "It was an important victory because I think that it's difficult to play here and to win here, because Arsenal are a fantastic team and have an incredible stadium.
"It was absolutely not a red card.
"He went into the tackle, anticipating the opponent and took the ball. It was no foul, no red card. This tackle is football. We will appeal.
"It is important for us to be there, close with them, and we will arrive the moment they lose points.
"Everything can change at the moment. We have the derby on 6 April and we need to arrive there with five or four points behind, it is okay."
