Paulo Costa is furious.
"The Eraser" took to Instagram on Monday to express his anger after seeing Israel Adesanya's postfight celebration at UFC 253 this past weekend, which included the 185-pound champion humping the challenger.
"I come here to talk about the action that ... the human trash did after our fight," Costa said in a video. "I didn't see when I was there in the cage, but I saw it now. And I disapprove, 100%. To me, this is mortal now. Nobody will stop me. Nobody can stop me. I am (coming) for you, Adesanya. I want my rematch - and you know I'm waiting for you."
Adesanya retained the middleweight title with a second-round TKO of Costa in the main event in Abu Dhabi, United Arab Emirates.
Costa, who was undefeated heading into his first UFC title shot, said earlier Monday that he's already focused on a rematch with Adesanya and believes it would play out much differently than Saturday's meeting.
