Not skipped over.
But just because a penalty is given, does not make it easier.
Would make more sense to list the penalties not given that should have been. If Man Utd had fewer of those..then that would be a stat.
Or indeed any ball going over the goal line by a yard or more and not being given a goal, that would be a stat
you could argue that Man Utd players are more clumsy..to the extent it would be impossible not to give a penalty..that I might believe
