Paulo Costa makes fun of Charles Oliveira's vision with viral video

Paulo Costa has emerged as the UFC's latest troll over the last year, taking shots at Sean Strickland, Henry Cejudo and many other UFC fighters. His latest victim is fellow Brazilian Charles Oliveira.

'Do Bronx' is fighting at UFC 280 this weekend, taking on Islam Makhachev in the most anticipated matchup of the year so far. There's an enormous amount of excitement surrounding the pay-per-view, and many fans are eagerly awaiting the main event lightweight title clash between Oliveira and Makhachev.

Costa recently posted a tweet making fun of his compatriot's eyesight. 'Borrachinha' quote tweeted a story about a woman needing to have 23 contact lenses removed from her eye, and said this about Oliveira:

"Bro 23? Don't even Charles needs too much lens to see"

Oliveira is known to have incredibly poor eyesight. 'Do Bronx' has said in the past that he sees three opponents in the cage without his glasses, and that he just aims for the one in the middle.

Tim Welch and Sean O'Malley are currently in Abu Dhabi for 'Sugar's' UFC 280 clash against Petr Yan. O'Malley posted a photo of the two wearing the Kandura, the traditional men's clothing in Dubai.

In response to Welch, Costa warned that if he and 'Sugar' were to arrive at his 'gym' wearing a Kandura, they would be shot:

"Yall very welcome but if u come wearing that clothes they will shot u immediately"

Paulo Costa and Sean O'Malley are both standup-based fighters and training together could provide both men with benefits. It would also provide MMA fans with incredible entertainment, with both men having unique and interesting personalities.
