West Bromwich Albion striker Peter Odemwingie feels Andrey Arshavin struggled with the ruthlessness of the locker room culture in England.

Arshavin has joined Zenit St Petersburg on-loan from Arsenal.

"Football is a man's game here and you have to be ready to show your character," said ex-Lokomotiv Moscow star Odemwingie.

"Even during training players don't hold back and if you are too slow, you could get injured. You need to be aggressive and hungry for success. I don't like players who stop once they've achieved a certain level of success. Even Arshavin could play a lot better, I reckon, if he motivated himself more."
