Robben is a primadonna and a drama queen.
They knew MEX would dominate any OT time and the Dutch were exhausted with the incessant heat & humidity.
So Robben had to do what he had to do.
The Mexican player did step on his foot and the was no reason for him to do so.
Aren't they all; well, at least most of them?
The Mexican defender made a mental error; just as Robben made a mental error when he jumped over the sliding tackle over the sliding defender just before the water break. Had Robben not jumped a penalty would have been awarded for tripping and no one would have complained.
