#10 Mirko Filipovic
Mirko is one of the best fighters ever to have stepped inside the Octagon. He was a former Pride FC Open-Weight Grand Prix champion and simply obliterated his competition. He was famous for his head kicks that knocked out his opponents senseless. But he failed to capitalize on all of this in the UFC. Mirko Crop was one step closer to the UFC belt after defeating Eddie Sanchez in a Heavyweight Title eliminator.
But the next fight against Gonzaga was probably one of the most unbelievable moments in the UFC as he was brutally knocked out by a monster head kick which was his most remarkable move. He then went on a three-fight losing streak and retired from the sport in the year 2015.
