I don't think he works anywhere near hard enough for the loan striker role at present. His goals let him off the hook from some poor performances.
He complained that he's not a target man and he's being used as one. Unfortunately, when you're playing as a loan striker you need to get in behind and be a target man.
He doesn't win anywhere near enough headers and his hold up play isn't very good.
At 20 he's young and has plenty of time to improve, but if he's not willing to graft he will never become a proper goal machine and I wouldn't pay anymore than £20m for him.
Although I'm not really inspired by the Traore deal this will at least put some pressure on him because Martinez was not willing to go with Jelavic at all. He just didn't fancy him.
