Paulo Costa has never been one to let a grudge die quietly. Now, after rebuilding a career many had started to write off, he’s gone back to an old target: Khamzat Chimaev.
The feud between the two had cooled in recent months, buried under injuries, scheduling chaos, and shifting divisions. Costa has used that time better than most. Once a fearsome wrecking ball at middleweight, his rise stalled brutally when Israel Adesanya outclassed him at UFC 253, handing him the first loss of his professional career. What followed looked less like a blip and more like a spiral.
Four defeats in five fights. The only win coming against Luke Rockhold, who retired immediately afterward. The aura faded. The title talk stopped. Costa, once a snarling contender, suddenly looked like a man searching for answers rather than opponents.
So he disappeared.
A year away from the cage can break a fighter or rebuild him. For Costa, it did the latter. He returned looking sharper, calmer, and far more dangerous. First came an impressive victory over Roman Kopylov, a performance that hinted the old aggression had been refined rather than lost. Then came the statement.
In his true light heavyweight debut, Costa detonated a head kick on the previously unbeaten Azamat Murzakanov, a devastating finish that felt like a line in the sand. This wasn’t just a win; it was a reintroduction. A reminder that his power and ferocity translate just fine at 205.
He hasn’t fought since that April breakthrough, but he hasn’t been quiet either. His eyes are fixed firmly on one name.
Khamzat Chimaev
The Chechen-born star has been linked with a move up to light heavyweight, a jump that would drop him into Costa’s new hunting ground. Costa, speaking to Mr. Gamble, made it clear he sees opportunity, not danger, in that rumor.
"I think that would be great for me," he said. "It would be wonderful for him? I don't think it would be very good, no."
That line says everything about where Costa believes the balance of power lies. Chimaev’s relentless wrestling and suffocating pressure have bullied opponents at welterweight and middleweight. At 205, Costa suggests, that edge starts to fade.
He drew a pointed comparison to another Brazilian star who dared to chase bigger men.
"I think for him it would be like Alex moving up to heavyweight, you know? I think the proportion is something similar, isn't it? The body type. I don't know. I think they're very light."
Alex Pereira’s brief foray into heavyweight didn’t produce the same magic he’s shown at middleweight and light heavyweight. Costa sees Chimaev facing a similar problem if he jumps too far, too fast. The message is blunt: size, frame, and power matter, and at light heavyweight, he believes Chimaev would be the one walking into danger.
Costa has rebuilt himself in silence and violence. Now he’s talking again, and he’s pointing straight up the ladder. If Chimaev really does come to 205, the Brazilian is already waiting, convinced that this time, he’s the one holding the advantage when the cage door shuts.
