A good player but not entirely sure how he will fit in. Definitely better as a #10, goes through periods of ups and downs out wide and, contrary to a couple of mentions, I don’t recall him ever playing a defensive centre midfield role. Big and strong, good on the ball but zero pace. Strength is getting on the ball and creating rather than providing much supply from the wing. Also did a turn up front in the latter part of the season when there were no strikers available, used his physique well up there. The Rangers fan above mentioned about the goal he scored whilst covering left back - this was in a European tie where he came off the bench at left back due to an injury crisis, he never played there again.
Main concern would be that he has played an awful lot of football over the last couple of seasons and his performance - understandably - dropped off quite badly for a couple of months after Christmas this year as he was almost certainly knackered. Seemed to largely stay clear of injuries despite this though which is good - hopefully that continues and he comes in refreshed for this season.
I expect his success will be dependent on how we look to utilise him for the price you can’t complain too much.
