Should arsenal start chamberlin instead of walcott?

Chamberlin scored a goal and was a constant threat in his first start for Arsenal (Albeit against lower opposition) last night, whilst Theo Walcott continues to dissapoint down the right for the first team. Is it time for a change I've always said that Walcott is not a winger he's a striker and  now that we do actually have someone that can play that position I think its time we did. We need to stop playing people out of position.

Who's with me?
