Gallery - Is this the most violent sporting event in the world?
Many have suggested that Conor McGregor and his UFC pals are a little too brutal to watch in action - but they look like fairies compared to the Calcio Storico battle that took place in Italy this weekend.
Calcio Storico (historic football) is an early form of football that originated in 16th century Italy, yet it died out as a 'sport until Benito Mussolini revived it in the 1930s.
Now an annual match is played in Florence, with four teams battling it out to be champions in a game that doesn't appear to have too many rules.
Punching and wrestling are tolerated (so long as it is one-on-one combat and not a mass brawl).
Yet the laws of the game that do not have room for head butting, chocking or elbowing your opponents. The latter of those rules may explain why Man Utd star Marouane Fellaini has not been invited to take part in the match just yet.
Punches, brutality and the odd head lock appear to be acceptable tactics to find a winning edge, with this year's final seeing the Azzurri (in a muddy blue kit) taking on Bianchi (sporting a white kit).
For the record, Azzurri beat Biacnhi in this year's decisive match, with the cuts and bruises sustained by all taking part likely to take several weeks to heal.
Fancy a go at this next year Mr McGregor?!
