The way we have conceded goals lately and in no small part to Mings casualness on the ball, you could argue that he needed to be dropped.
It was almost guaranteed that he would make one huge fuck up per game, either caught in possession or an awful stray pass. Maybe the injury was coming for a while and hindered his game.
Either way the rest may do him good. Almost the same could be said about SJM needing a break also
