Ultimate Fighting Championship (UFC) middleweight contender Paulo Costa is the toast of the middleweight town these days, thanks to his technical knockout win over Johny Hendricks at UFC 217 earlier this month in New York City.

Cezar Ferreira is not impressed.

In fact, “Mutante” (12-6) went so far as to call Costa’s 11-0 record “manufactured” after several years recycling cans on the Brazilian circuit, which led him to an easy fight against a bloated welterweight at the tail-end of his career.

Ferreira breaks it down for MMA Fighting:

“This guy… his career is so fake that even his nickname changes all the time. He was ‘Golden Boy’, and then ‘Borrachinha’, and I don’t know what his name is now. He’s trying to be like (Conor) McGregor. He’s an asshole. He’s a lie. His career was manufactured. Seventy percent of his fights were in events inside gyms, where he fought and beat up random doormen. That’s why he has that record. Check his record on Sherdog, nobody knows any of those guys, and he’s acting like he’s the middleweight champion already but hasn’t done anything. The only real fighter he fought was Johny Hendricks, but he’s a welterweight the size of his legs. Come on.”

I thought “Bigg Rigg” was supposed to be tougher than Vitor Belfort?

Part of Ferreira’s issue with Costa was the latter’s callout of the aforementioned “Phenom,” which upset “Mutante” because Belfort and his team helped train “Borrachinha” and bring him to the big show.

No matter. Costa has already moved on from his Brazilian rivalry and now targets middleweight contender Derek Brunson, who judging by replies like this one, can’t bothered with fighting the “slow and gassy” up-and-comer.
