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

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.

The UFC’s October 11 return to Rio de Janeiro just got a main event, a pivotal lightweight showdown between two of the most technically refined Muay Thai stylists in the division, if not the entire UFC.
