Jiri Prochazka has his sights set on regaining the UFC’s light heavyweight title.

At last weekend’s UFC 313, Magomed Ankalaev handed Alex Pereira just the second defeat of his UFC career when he triumphed over the Brazilian two-division champ via five-round decision inside the T-Mobile Arena in Las Vegas. One interested observer to that contest would have been the former 205-pound champ Prochazka, whose title ambitions had been blunted by two separate losses to ‘Poatan’ with a third fight unlikely as long as Pereira held the belt.

But now with a new sheriff in town at light heavyweight, Prochazka has has crosshairs on Ankalaev — particularly after the Russian suggested on social media that he is a “terrible fighter” and a “fraud.”

“One thing what I can say to Ankalaev, he can think whatever he wants but I know that the only person who’s a fraud is him,” he told Ariel Helwani, as reported by MMA Fighting. “Because when I met him at the UFC Performance Institute in Las Vegas, he was there, he was very nice, he was friendly [saying] ‘hello, nice to meet you, all good’ and right now he’s a superstar and a big gangster.

“Right now, he’s playing this game and he is hyped and I understand. He won the title against the worst performance from Alex Pereira. Only fraud person here is Magomed Ankalaev.”

He added: “I don’t care about this guy. I just want to go and take a title. It doesn’t matter about him. Right now, he is the champion but I think nobody likes that and nobody respects that he is the champion.”
