So, this is a fight between hypotetic fighters, that happen in a street. There are no rules, but let's consider the fighters won't take the fight to the ground, nor use dirty moves, like kicking the balls, biting, etc.
It's a bare knuckle fight, in a limited, but not too small area, something of the size of a boxing ring. Both fighters are experts on their respective fight style and are allowed to use any techniques they want (except the ones I said above). Bloodlusted and no morals, fight ends with K.O.
Also, both fighters with 1,80 m height and 80 kg weight.
