Yaya's penalty slashes Chelsea's lead to just three points... but Aguero's knee injury sours City's night

Manchester City cut the gap on Premier League leaders Chelsea to three points but it came at a huge cost with star striker Sergio Aguero limping off in tears after sustaining a potentially-serious knee injury near the start of the game.

Aguero received sympathetic applause from stunned City fans as he sadly made his way around the edge of the pitch to the dressing-room after receiving nearly five minutes of treatment.

His eyes were clearly watery both because of the pain and also the prospect of missing Wednesday night's vital Champions League clash away to Roma that will help define City's season.
