Neymar is one of the world's best footballers, and the Zambian defence were sure to be fearing the Brazilian's talents when the two sides met in an international friendly earlier today (Tuesday).
What they wouldn't have been expecting was a pot-shot to the privates, which is exactly what happened when Emmanuel Mbola stopped playing after the referee's whistle.
The Barcelona star decided to continue however, and unleashed a fierce volley which connected with his opponent - standing just a few yards away.
Unsurprisingly, the Zambian players were far from happy with what they'd just witnessed, as Mbola rolled around in agony on the floor following the 'nut shot'.
David Luiz was forced to step-in and play an unlikely peacemaker, as a number of the Zambians took particular exception to the incident which had just occurred.
Neymar protested his innocence, and it all settled down rather quickly - but not before a brilliant video had been created for us all to enjoy (apart from Mbola, of course).
So, our sincere apologies to the man in question, but watch the eye-watering video at the top of this story...
