Kalou said: "Drogba is showing how to do it. He's showing that he has a big personality. He wasn't happy but when he's on the pitch he delivers everything.
"He has shown that a lot and that's why everybody has respect for him. It's also why he is one of the best strikers in the world."
"Everyone has to prove himself for a new manager. The competition here is really hard and everybody knows that.
"Everybody tries their best to bring more quality to the team. It's what we all want to do.
"I am training hard. If you have the chance to get on the pitch, you have to take it and do your best to keep your place.
"You have to show to the new staff that you can be an important player for the team."
