"What should have happened first is for Rio, the PFA and Manchester United to attend this hearing on Monday, let the FA listen to his explanation, and then take a course of action. They have not even given him any credit for the fact he tested negative 36 hours later. I think it is completely unfair to penalise Rio until he has had an opportunity to explain exactly what has happened. I have spoken to him and as you can imagine he's not best pleased."
