I would like to keep him, but onto your question... I think for him to be effective in any club the manager has to clear him from most of his defensive responsibilities. Once he does a few sprints back and forth his legs are dead, and that will affect his passing, dribbling and everything else. Russia did that and it worked pretty well. (well Arshavin was good anyway) I don't think the issue of playing him centrally vs. wide is as important as some here claim. Some of the best games he's played in his carrier have been for us playing wide(ish).
