If I was Sheffield United I would NOT allow a convicted rapist, now out from jail on licence, to train with the squad. In effect he has served only half his sentence so far and is only out of prison to serve the remainder of his sentence. Any misbehavior and he is back inside. He committed a very serious offence and so should be made to pay for this. He should not have committed rape. Come back later, maybe?
