What if Rangnick comes in and said Ronaldo is not good enough for his pattern of play so he stays on the bench? Of course Ronaldo will not be willing to sit on the bench and he clearly showed his displeasure by storming into the dressing room straight after the match against Chelsea. A time on the bench will be like a life sentence for someone as influential as Ronaldo but in big games where Man U needs to defend more he may have to make do with a place on the bench. Ronaldo is a big game player so that makes it all the more frustrating.
