Chelsea boss Jose Mourinho insists Manchester City cannot use Sergio Aguero's injury as an excuse for their stumbling title tilt.

Aguero is Manchester City's top scorer with 19 goals this season, but has been ruled out for up to eight weeks with a ligament problem.

"They have a magnificent squad, full of top players and end products - not young people," he said. "If one doesn't play, he plays another. City went to Rome (in midweek) and played a Champions League final (they won 2-0 to qualify for last 16). They were there without two or three.

"They have a very good squad I don't see if one player is missing, they have a problem."
