I may be wrong, having been to mainly away games last year, but at leeds away and forest away he was pretty dominant in the air. He won more than his fair share of headers when up against CB's. Aswell, as scoring a header against forest.
Not saying he should be a definite purchase, but would happily disagree with anyone who says he didn't contribute to the team.
Think the formation and tactics weren't set up to win knock downs and flick on's which he provided. On that basis he isn't right for us but he's a good striker. Wouldn't be surprised if he is picked up by another championship team and goes on to score 15 goals a season.
