Every man knows what it feels like to get kicked in the nether regions and we all know that it is bloody painful.
When there is a mass brawl, like this one between Stafford Rangers and Frickley Athletic, during a football match, those involved run the risk of getting a kick or a punch in that particular area.
Brawls are always quite fun to watch and I imagine that this is what the touchline scuffle between Lyon and Tottenham would have turned into had they been allowed to continue on Thursday night.
Stafford and Frickley, of the semi-professional Northern Premier League Division, seem to have annoyed each other so much that instead of playing football they decide that fighting each other is the only way to settle matters.
Keep your eyes peeled on the top right hand corner of the screen, though, and watch the isolated incident between a Stafford Rangers player and the Frickley Athletic goalkeeper. Away from all the action, the Stafford Rangers player manages to land a cheeky kick in the testicles of the keeper.
It is downright cowardly and the referee who protects the Stafford player should do the the right thing and step out of the way so that the goalkeeper can adminster his revenge on the perpetrator.
