Haha, that's madness. They got him for free along with a huge amount of money. Surely he's not playing that badly? It's true that when the goals dry up, he doesn't provide much other than his great work rate but Christ, it's a bit early for talks of selling him off.
I still maintain that he won't be half as successful now that he won't have that endless amount of chances. He can still be a decent striker though, his form will surely pick up.
