With UFC 320 on the horizon, Alex Pereira is leaving no stone unturned for his much-anticipated rematch against Magomed Ankalaev. 'Poatan's' unique grappling drill for the upcoming contest, however, has fight fans concerned.In their original meeting at UFC 313, Ankalaev used his superior wrestling to force clinches and pose a persistent takedown threat. This severely affected the Brazilian's work rate on his feet, allowing his opponent to land damaging strikes of his own.While Pereira was largely able to stop Ankalaev's takedown attempts, he was unable to mount a meaningful offensive. At one point in the fight, the reigning light heavyweight champion even landed a clean punch that stunned the famed kickboxer.Coming into the rematch, 'Poatan' appears intent on further bolstering his grappling capabilities. A recent Instagram story by the fighter shows him defending takedowns from multiple opponents, one after the other.Fight fans, however, are not happy with his training methods, with many taking to social media to note their opinions.Check out Alex Pereira's training drill below:@ZamCorleto wrote:"Hmmm, idk Big Ank by KO!
