12. Paulo Costa
Israel Adesanya destroyed Paulo Costa with a second-round TKO at 2020’s UFC 253. It was an unbelievable display from the Nigerian-born New Zealand native. However, Brazil’s Costa couldn’t comprehend that ‘The Last Stylebender’ had dissected him. ‘Borrachinha’ proceeded to unleash a host of embarrassing excuses in the weeks that followed that did nothing to improve his status in the eyes of fans.

He first claimed to have suffered an injury before the fight. This is a go-to, get-out clause for fighters when they lose. Needless to say, not many bought this and put it down to sour grapes. Then he tried to act as though Adesanya hadn’t totally destroyed him and continued to call for a rematch that nobody wanted except for him. This proves sometimes you just have to admit defeat and stay quiet.
