Arsenal v West Ham: Koscielny and Kallstrom start against Hammers

Arsenal take on West Ham at The Emirates and will be bolstered by the return of Laurent Koscielny.

The centre back returns following injury, while new signing Kim Kallstrom will make his first start for the club after making an appearance last Saturday against Wigan in the FA Cup.

West Ham are without talisman Kevin Nolan yet will be aiming to keep Arsenal out of the top four with a win tonight.
