Kompany in race against time to face Roma.

Manuel Pellegrini has ruled the Manchester City captain out of the next two league games, as he awaits the medical team's assessment of the Belgian's hamstring injury.

Manchester City could be without captain Vincent Kompany for their vital Champions League clash with Roma.

The Premier League champions came from behind in dramatic fashion to beat Bayern Munich 3-2 at the Etihad Stadium on matchday five, and must now win against the Serie A side away from home to progress to the knockout stages.

But Manuel Pellegrini has ruled the Belgian out of league games against Sunderland and Everton and is facing an anxious wait over the centre-back's fitness ahead of the must-win game in Rome on December 10.

"Vincent Kompany is not able to play against Sunderland or against Everton, that’s sure," Pellegrini said. “We’ll see if he arrives against Roma, but that will depend on the opinion of the doctor.

"It’s very difficult, because I cannot say without the opinion of the doctor how his injury will improve in the next days. It depends what degree of muscle injury he has.

"It’s very difficult to know in this moment if he can play in Rome."

Pellegrini has a decision to make on who to play in central defence against Sunderland at the Stadium of Light on Wednesday.

With Eliaquim Mangala suspended, Bacary Sagna could deputise at centre-back alongside Martin Demichelis, while Dedryck Boyata is also a candidate for a start.
