This.
If we don't sign anyone else, I'd play him LW a couple of games to give Jonas a kick up his arse, then move him to play off Carroll. If we sign a decent striker (say, Keane on loan), then I'd play him LW for the rest of the season.
I do think HIS best position is in the hole, where he can roam and do whatever the fuck he wants, but as our option out left isn't good enough, he'd be most useful out left.
