Fresh off beating a 200+ lb. Paulo Costa, Marvin Vettori already has his eye on Israel Adesanya, promising TMZ Sports he'll "f*** him up" the next time he sees Izzy.
Presumably, Marvin means in the Octagon ... and not on sight.
We talked to the UFC star outside a Beverly Hills restaurant Tuesday night -- just 3 days after the Costa fight -- and asked the 28-year-old fighter about Adesanya calling Marvin's fight with Paulo a "s*** show."
"He's full of s***. He never gives me credit, but he knows. He knows what's up. I'm the only guy who's gonna beat him, and eventually, I will. It's just a matter of time," Vettori says.
He continued ... "I saw clips of that video man, he's full of s***. I'm gonna f*** him up next time I see him, that's for sure."
The Vettori and Adesanya beef is nothing new. The men fought twice previously -- in 2018 and 2021 -- with Izzy winning both by decision, though, Marvin believes he was the true winner of their first fight in 2018.
