On the down side:
He's not quite set the world on fire, and his hold up play's been pretty bad.
He can't jump for toffee (or can't be bothered - it's hard to know)
On the plus side:
Good attitude (seemingly)
We're short of tall strikers (no pun intended)
He's hardly been a disaster
I'd keep him unless there's a clear replacement for him with proven ability - and that's not many of those about. We need players with a good attitude.
And swap him for Torres + 5 million in the blink of an eye though.
