Chelsea boss Luiz Felipe Scolari has warned Nicolas Anelka he could leave in January.

Scolari said: "Of course it's important for us to have (Didier) Drogba fit and ready, because he's one of the best players in this position in the world - and more.

"His qualities are different to Anelka. He holds the ball up more and uses his body more than Anelka, although Anelka has more speed.

"But he brings different qualities for the Chelsea team and this is important.

"What I want from all my players is that they're happy they play for Chelsea, rather than only if they're playing in the team. I want Drogba clean and ready. Anelka has gone three months without an injury, so the choice is mine, whether it's a, b or c.

"This is Chelsea, we're a team, a group. If players are unhappy then in January they will be out. Any player. They need to understand they all win as a group. Any player who's here for themselves needs to go somewhere else."
