Why should he tear up his contract? We offered him the terms he's on and as long as he doesn't breach the terms of his contract then he's entitled to every penny.
He has previously attended for pre-season tests and I'm sure that he'd return if required to do again. And he can't be forced to go anywhere on loan that he doesn't want to. The fact that a club is willing to pay 20% of his wages is better than us paying 100% for someone who is surplus to requirements.
This is a problem of our own creation and we have to suck it up I'm afraid.
