I don't know what he was like before, but I've just completed my first season with Forest and he came back strong from the long lay-off + helped me to win the Championship!! I'm at work so I can't give you any stats - games/goals/assists - but I do remember him making a significant contribution when he came back from injury.
He's also started life in the Prem quite well too. A couple of goals and assists in the first 5 games
