Charles Oliveira made every UFC Rio fan pleased and perhaps put himself up for a big rematch. In the main event on Saturday, the former lightweight champion added to his amazing legacy by beating Mateusz Gamrot in less than two rounds with a rear-naked choke. Oliveira now has 17 submission wins in his career, which is a record he already owned. Oliveira stayed undefeated in Brazil, bringing his record to 18-0 in his home nation. This was the first time Oliveira has ever fought in a UFC main event in Brazil, which is hard to believe. Oliveira then asked for a rematch with Max Holloway. The two fought a long time ago, in August 2015, and the fight ended badly when Oliveira hurt his shoulder. Oliveira now wants a chance to get that loss back, with Holloway's BMF title on the line.
