Manchester City boss Manuel Pellegrini admits skipper Vincent Kompany is a doubt for the derby against Manchester United.

Kompany is doubtful for the clash at Old Trafford after feeling his hamstring tightening in defeat at Crystal Palace.

Pellegrini is hopeful the influential defender will pull through but he will undergo a fitness test.

Pellegrini said: "We will see tomorrow if he can play or not. It is always better to play with Kompany but if, for different reasons, he cannot play not we have a squad and he must be replaced."
