I was not impressed when he was at Boro.5 goals in 71 games for Middlesbrough and 6 goals in 71 for Wolves is abysmal for an attacker/winger. He brings absolutely nothing to this team and his track record shows he has no end product to this day.
His overall stats: 168 appearances 13 goals 28 assists (8 seasons of football)
I am impressed now although I must admit that I thought his current stats would be better.
Wolves though are generally a cautious side. I think he'd be a great player for City's squad. I have changed my opinion of him this season. I think he is one of the very few players in the Premier League who literally will terrify an opposing defender.
