The Sunderland fans seem to rate him, been linked to Borussia Dortmund, a bit of googling shows articles about him being close to breaking into the first team, etc.

Really excited about this guy.

just looking at the clips now- he seems much stronger on the ball than Riera. A bit like a Tim Brown plus plus, seems strong, able to find the net, when he scores that goal he has pace taking the ball forward.
