After victory at Manchester City, Chelsea midfielder John Obi Mikel insists the Premiership title can be clinched.
"Manchester United are a good team but we know they will drop points. Joe Cole said recently that we are the silent killers and we have to keep going."
There were questions about Chelsea's spirit after their midweek Champions League defeat by Fenerbahce.
But those questions were quickly answered by this display against City.
Mikel said: "Because we lost one game people think the spirit is not good but the spirit is good. In this game it could have been five or six-nil. We have a big squad, big games coming up and big players."
