Whether it is spontaneous or premeditated it's really all the same
Did Henderson milk it? Yea maybe, but it looked like from my broadcast that the blow did draw blood. Maybe that was from him only biting his tongue but I’d have reacted the same way in that situation, the Colombians were playing very dirty and the ref had no inclination at that point to stop it so Hendo milked it for what it was worth.
Neymar actually had a reason to be upset as he was stepped on with a studded shoe, but he certainly took it to that next level of being shot with a shotgun at close range type of rolling around which is what turns people off. I don’t know that Neymar is looking for instances in which he can try to con refs, I think he genuinely gets roughed up so much that he has decided to make a show no matter what to try and make the most of it.
