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