Renato Moicano says Rafael Fiziev is "the worst fight in the rankings" for Charles Oliveira and worries what will happen at UFC Rio.

Renato Moicano is worried by Charles Oliveira's decision to face Rafael Fiziev at UFC Rio de Janeiro. As the former lightweight title challenger sees it, the match-up might be counterproductive for 'Do Bronx's' career.

Charles Oliveira will face Rafael Fiziev in the main event of UFC Rio on 11 October, in an intriguing, unexpected match-up. The fight marks Oliveira’s first contest in his native Brazil since 2020, and will see the former lightweight champion aim to bounce back from his brutal knockout by Ilia Topuria.
