During their first meeting at UFC 313, the Brazilian suffered a unanimous decision loss to the Russian.Alex Pereira makes bold claim about Magomed Ankalaev rematchAlex Pereira is convinced his rematch against Magomed Ankalaev will play out much differently than their original fight. As the former light heavyweight champion sees it, his game has developed enough for him to win using more than just his striking.For context, at UFC 313, Ankalaev utilized his wrestling to force clinches and present a persistent takedown threat, essentially denying the famed kickboxer the opportunity to mount an offensive on his feet.During an interview with Ariel Helwani in March, Pereira issued a bold message to his doubters via his coach, Plinio Cruz:"I can't wait for this moment [rematch] to happen again, and it's going to be a very different fight. That day, it was not the same Alex Pereira. So, if the regular Alex Pereira comes, it's already more than that, but imagine if he is different. It doesn't have to be a knockout. I feel I have enough game to do whatever I want with this guy."
