Conor McGregor responds to Ilia Topuria's call-out after UFC champion's 'balls' comment

UFC legend Conor McGregor has responded to a challenge from new champion Ilia Topuria.

Topuria won the world title that McGregor once held at UFC 298, knocking out Alex Volkanovski. Just moments after UFC boss Dana White wrapped the featherweight world title around his waist after his win, Topuria called out McGregor, saying: "Conor McGregor if you still have some balls, I will be waiting for you in Spain."

Topuria also said he would be willing to move up in weight to fight McGregor, adding: "Who said that I want to fight him at 145? There is no weight if I fight him, he can choose it. I will give him that option, if he feels he is ready for this level of competition then he can choose the weight. I can choose the place."

McGregor and Topuria were both doing really well before their big featherweight title fights. They had each won six UFC fights, had
