The veteran says they're not as good as they used to be.
He said: “The fixtures and where we are in the table doesn’t lie — we’re not as good as we used to be. We used to have a fortress here [at Stamford Bridge] and for whatever reason we’re just not doing it. It’s something we must all put right.
“You know a derby against a very good Tottenham side is going to be tough. But I don’t think we were at it enough. We had to play more with the urgency we showed against Napoli."
