Fans are hilariously reacting to a recent video of Alex Pereira maintaining a calm face while riding a roller coaster.'Poatan' uploaded the video to his Instagram story, and his expression barely changed throughout the duration of the roller coaster ride. Fans reacted to his steely demeanor on Twitter and brought up his longtime foe Israel Adesanya with humorous remarks."He’s only happy when he beats izzy"Reddeadhood@Reddeadhood2@AjDuxche He’s only happy when he beats izzy@AjDuxche He’s only happy when he beats izzy"this man only smiles when he beats IzZzy I swear"Sunburnt Icarus@DystopiaEnjoyer@AjDuxche this man only smiles when he beats IzZzy I swear 191@AjDuxche this man only smiles when he beats IzZzy I swear 💀 https://t.co/CIwMXeaoa3"The only time he smiled was when he ruined izzy's life"miki@MakarovaMishka@AjDuxche The only time he smiled was when he ruined izzy's life@AjDuxche The only time he smiled was when he ruined izzy's life"Roller coaster vs. Ruining Adesanya’s career…"Irving Niño@IrvingGiancarlo@AjDuxche Roller coaster vs. Ruining Adesanya’s career…@AjDuxche Roller coaster vs. Ruining Adesanya’s career… https://t.co/dLjX4EOT2h"The only joy in this mans life is punching Izzy in the face"Sebastian Yaremchuk@SebaYaremchuk@AjDuxche The only joy in this mans life is punching Izzy in the face@AjDuxche The only joy in this mans life is punching Izzy in the facePerhaps the reigning middleweight champion will continue posting entertaining videos for his fans.

However, he also raised a question for his viewers:"It would seem as though we redo Adesanya and 'Poatan'. You guys would really enjoy that match. But are we a little naive to act as though that [fight] is a forgone conclusion? What rematches have we seen in the past that were immediate? Were announced immediately?" [1:52 - 2:24]It will be interesting to see what the UFC has planned for 'Poatan', but Sonnen raised a valid point - the fight not being announced yet could also mean that an Adesanya-Pereira rematch is not on the cards, at least for now.
