That, coupled with his expiring contract, has the French international looking for work elsewhere.
Anelka has had a very good career at the Bridge, and he will be a tough player to replace. He can play any attacking position and will be a great addition to a mid-level club.
How will Chelsea go about replacing him? He is a dynamic presence, and he can finish as well as anyone. As a result, Chelsea will probably receive a decent price for him, giving them a pretty large budget this January.
I have compiled a list of nine players Chelsea should consider while bolstering their attack.
These aren't necessarily players who would fit into Anelka's role—rather, they are simply attacking threats Chelsea should look at (the defense is a completely different story).
Note—not all these players have been linked to Chelsea, but Andre Villas-Boas should definitely consider each of them.
