Maybe I'm completely wrong with this, but has he ever really relied much on pace? I thought he was a fast player when he joined, but someone corrected me when we signed him that he's actually not that quick.
It's shocking for a player to just lose your quality over night, as he did. Torres is an example - but I can't think of another example personally. I do think it's a matter of confidence, which is something he just doesn't have at the moment. The chance he missed against Chelsea - created the space and when 1v1 with Courtouis, he just sliced it completely.
As I said, £15million is as far as I'd go. But I also said, I'm probably 100% wrong and if it wasn't a hypothetical situation and we were actually offered such a deal, I may not think this.
