Manchester, England (SportsNetwork.com) - Manchester City striker Sergio Aguero is set to miss the next six weeks because of a knee injury, the club revealed.

Aguero has been the driving force behind a City team that resides in second place in the Premier League, three points back of leaders Chelsea. However, he will miss the club's busy festive program while leaving huge shoes to fill in the scoring department.

The Argentina international leads the Premier League with 14 goals this season, but he limped out of City's 1-0 win over Everton on Saturday after just a few minutes with ligament problems in his knee.

The injury is not as serious as initially feared, but it means that Aguero will take no part in Wednesday's crucial Champions League match with Roma, while he will also miss league matches against Leicester City, Crystal Palace, West Bromwich, Burnley, Sunderland and Everton and possibly the Jan. 17 meeting with Arsenal.

Manager Manuel Pellegrini will now rely on Edin Dzeko to lead the line, while the boss got some good news with the possible return of both Vincent Kompany and David Silva from injury.
