Manchester City boss Roberto Mancini knows they face a Champions League must-win clash with Villarreal.

After drawing with Napoli and losing at Bayern Munich, the visit of Villarreal to the Etihad Stadium on Tuesday is now a must-win game.

Mancini said: "We have four games left and to have a chance of progressing we need to beat Villarreal. We need 10 points.

"The group we are in is strong, so maybe we are okay with just one point from two games - but the next two games must bring us six points. That will be difficult.

"What we must do is win our next game and after that everything could change."
