All indications appear that he doesn't want to play for us. He's under contract and if he wants to leave, he should be the one to forfeit any financial benefits that contract may include as he is technically breaking it by not having the right attitude to play.
If he wants out, then hand in a transfer request. It's that simple.
It's not personal, it's business.
And I haven't questioned that. I just hate the "fuck you" attitude.
