"Is English a requirement to be cool?" - Fans pick sides after Islam Makhachev claimed speaking in Portuguese makes Charles Oliveira less marketable 

Islam Makhachev's upcoming fight with former lightweight champion Charles Oliveira is generating all the hype. Like most high-profile bouts, this one does not lack any tension between the two opposing camps.

Appearing on the DC & RC show with Daniel Cormier and Ryan Clark, Makhachev took a dig at Oliveira's linguistic ability and cited it as something that held him back:

"I don't know, I don't understand this guy. He tried to always make [it about] money. But this guy doesn't speak English. Nobody understands this guy, he doesn't speak English. English is important if you want to make money, you have to speak some language everybody understands. Nobody understands what he's saying."

One fan responded along the same lines as Makhachev's earlier jibe at Oliveira:

"You don't even understand what Oliveira is saying without a translator but cooler? Ok lmao. Keep hating."

Other fans joked how they understood Oliveira better than his counterpart, as Makhachev himself converses in broken English and is perhaps not as fluent as his teammate, Khabib Nurmagomedov:

One fan also appreciated Charles Oliveira's ability to sell a fight better than his less experienced opponent:

Another fan seemed glad that Islam Makhachev was engaging outside the octagon, too, having been a very low-key fighter before his imminent main event fight. @CranberryTyler liked the change in Makhachev that saw him trash talk his opponents:

Charles Oliveira perhaps buckling due to naysayers and trash talk, says Chael Sonnen

Despite 'do Bronx' being a former champion and having dominated many more ranked opponents than Makhachev, he finds himself booked as the underdog in the championship fight.

Perhaps that, and Makhachev's comments, are getting to the Brazilian. Chael Sonnen weighed in on the fight on an episode of Beyond The Fight and voiced his deduction of Charles Oliveira's mindset:

"I think Charles is pi**ed off. I think Charles is pi**ed off [because he] was the champion, [but] hasn't lost. He was the champion and hasn't lost, and he's a three-to-one underdog. I think that upsets him — I think that insults him."
