He is a bundle of energy, which can be useful, but doesn't nearly make up for the fact that he has zero brain, can't control a ball or pass it, and cannot be relied upon not to fly into a rash tackle. So, about that...Apparently available for 45/50 million in January. He is arguably one of Chelsea most consistent players so not sure why they want to sell.
I think he would be a great fit for us and have done for a while.
