I've only ever seen him play two full games to be honest, and it was at a time when Saints were drawing every week but he did look like a player with alot of potential.
I was expecting him to have made an impact in the PL when I suggested he could be in the squad, but one thing I would say is, Arsene Wenger is the manager I admire and respect the most in the world, and if he can honestly say that this player can go to a WC and make a positive impact, then that's all I need to hear.
Wenger gains nothing but a broken kid if he goes and disgraces himself, or isn't up to it.
