'The Highlight' slammed 'Do Bronx' on social media, but came up to him after the event to congratulate him.On MMA Fighting's Trocacao Franca podcast, Charles Oliveira said:"The guy [Justin Gaethje] is talking a bunch of crap the entire time, and when we meet face-to-face he says he has all the respect for me and what I do. And two minutes later he’s saying he’ll break my face and saying a bunch of stuff. These guys hype things up and try to sell the fight with something they are not. If you’re a humble guy, if you’re a respectful guy, you have to sell the fight that way. If you’re a guy that talks crap, you have to sell the fight talking crap the entire time – to my face and behind my back.”Justin Gathje also reacted to Oliveira's comments via a tweet.
