He'll never be a Heskey under Wenger that's for sure. But do you remember young Heskey? He was, although big, a fairly skillful winger/striker that had a lot more in his locker than pure strength and work rate.
The work rate can be scared into a lad, say JET under someone like Sam Allerdyke or Mick McCarthy, but Wenger is neither the type to scare someone or to want that sort of player. I mean, Bendtner would have been a target man years ago under many other managers, but for us he's still a decent footballer and is encouraged to keep on taking on players. He'll no doubt be a better player because of this, albeit maybe not skillful enough to really establish himself under Wenger, but if he's sold to a "lesser" side he'd be their main focus and score more than 15 goals every season.
Anyway, trying to look for examples of young Heskey, failing due to going off on a Bergkamp vid spree, what a player, I found this video:
Another example of a high scoring away draw we should have won. But in a season we won the league:drool:
