We've got to make sure it's safe, that's all. There'd have been no trouble at the derby if Van Persie hadn't screamed abuse at the City fans and Ferdinand pranced about like an idiot in front of them. Sharpened coins? Did all the police's forensic team actually find a sharpened coin? Don't think so - and if you noticed, the scratch he had wasn't on the sides or back of his head. It's position told you exactly where he was standing when it struck. We should never, ever throw anything at a game, but if people ask for it they really shouldn't be surprised when it happens...
