As he's got 1 year left I imagine we will have to keep him as his wages would be too high for most Championship clubs.
Having said that I think he's good from the bench in the Premier League if we need a goal, in the Championship he didn't contribute much other than his goals and wasn't as effective as Kanu in terms of hold up, passes etc. However, he's more of a natural finisher which may be vital in terms of grabbing points etc so it's not a bad situation for all involved.
