Chelsea boss Avram Grant has questioned Didier Drogba's attitude upon his return from his African Nations Cup campaign.

Grant said: "He was injured before he went to Africa and then when he came back he was not so good. Not just on the physical side but also on the mental side."

However, he added: "Against Arsenal Didier was very good. In the last 10 games we've scored a lot of goals and it's good that the right players, at the right moment, are in good shape."
