Vincent Kompany
Kompany suffers knock in training.

Manchester City skipper Vincent Kompany could be a doubt for his side's potentially title deciding clash with Liverpool after limping out of training on Saturday.

The Belgian international hobbled off the training pitch supported by teammates after landing heavily following a collision with Micah Richards during a routine free kick practice.

Kompany was pictured clutching his knee but the nature or the severity of the knock has yet to be confirmed by the club.

Brendan Rodgers' side sit at the top of the Premier League with a four point lead over third placed City, who have two games in hand. Their visit to Anfield on Sunday is likely to play a pivotal role in deciding who is crowned champions in May, but the loss of City's influential captain would hand Liverpool a significant boost.

With Matija Nastasic still unavailable due to a knee injury of his own, manager Manuel Pellegrini could face further defensive headaches with Martin Demichelis and Joleon Lescott his only other natural options at centre half with the latter having not started a game for City since March.

Liverpool enter tomorrow's game in relentless form having won their last nine games in a row, fuelled by the exquisite form of the Luis Suarez and Daniel Sturridge. The duo have struck 29 and 20 league goals respectively and have been the catalyst behind the Reds' push to win their first league title in 24 years.

Should Kompany fail to recover in time for Sunday's clash, Pellegrini may look to Javi Garcia to fill the void at centre half.
