He's a mental midget. Is what it is. Said it when he was 'on form' - it doesn't matter because he's soft mentally and as soon as he faces the tiniest amount of adversity, this is what happens.
He's one of those odd players who would actually look OK in really good sides, because he's a confidence player. But for a side trying to get to that level, he's a complete liability.
If we can mug off a lower half Prem side for a decent fee, we should be all over it. And he'd be an Ashley Williams-esque flop to whatever one of those clubs he goes to.
