There's talk about having similar clauses in these contracts by definition. But obviously part of a footballer's value is his brand and the amount of money he generates. Pogba hasn't played for us, but he probably has still made us a bit of money.
At this point I'm just sad about it really. I think the guy probably wants to play. I mean, surely playing is more fun than rehabbing. If he's still not fit now, I think his body is gone and we won't see him get back to anywhere near his former level.
