I think he can't do it anymore - maybe he realises it maybe he doesn't. He's in a huff with GON because he's got Doc ahead of him (as I would be) and he's also not prepared to take a paycut, however minor, to move (as I wouldn't).
However no matter how big the huff, or even how valid it is, you're paid to train hard every day and be available to play football, and if you refuse then tbh you should be liable for the sack with no pay off. I don't really care how unfortunate the series of events leading up to it was. You're a footballer, the very least you can do is agree to be available to play football. Thanks for the couple of seasons of excellence, but if you want to be a cunt then you can fuck off and do it in your own house on your own time and not get paid for it. It's not as if we're protecting a transfer fee or anything. Just fuck him off
