​Paulo Costa is itching to keep his momentum rolling in the UFC light heavyweight division. Yet it hasn’t been easy to find the right fight for the final fight of his contract.In a recent social media tirade, Costa, 35, vented his frustrations over being sidelined. “Borrachinha” last fought in March, when he scored an impressive knockout of the previously unbeaten Azamat Murzakanov. The layoff has tested the patience of the Brazilian contender.AdvertisementAdvertisementAdvertisementSpeaking in-studio in Las Vegas on Monday’s edition of “The Ariel Helwani Show,” Costa revealed he was contacted about replacing Khalil Rountree Jr. in the UFC Abu Dhabi main event on July 25 against Magomed Ankalaev. Instead, Costa declined what would’ve been the final fight of his deal, prompting Bogdan Guskov to take Rountree’s place.”I’m looking for a fight, but not a short-notice, five-round fight in Abu Dhabi,” Costa told Uncrowned. “They offered that fight just to get a no as an answer from me. They extended [my contract] for six months [because of that]. I think there were some misunderstandings and mistakes — I don’t understand exactly how they configure these things, and extensions and stuff. I’m not a lawyer. You need to know the small letters on the contract stuff. But I’m a fighter. I just fight.”Dana White and [UFC CBO] Hunter [Campbell] came up to me after my last fight and said, ‘I think this is the biggest victory of your career.’ Maybe. And now, nothing’s happened.AdvertisementAdvertisementAdvertisement”I’m looking for a fight, and they didn’t offer me a proper fight,” Costa continued. “Give me eight weeks to fight somebody else. I don’t care who. I even opened the door to middleweight or heavyweight. Of course, I’d prefer to fight for interim belt. I think I deserve that opportunity right now. If you look at the history, people who come from losses don’t fight for the belt right after. So, I’m able to fight [for it].”Costa’s light heavyweight move came at a perfect time, considering the result.The 205-pound division fell into immediate disarray the same night Costa beat Murzakanov. At UFC 327, Carlos Ulberg pulled off a miraculous knockout of Jiri Prochazka to become the new champion. Ulberg unfortunately tore his ACL in the process, throwing the direction of the division in question, and opening up the idea of an interim strap.At this point, Costa simply wants to wrap up his current UFC contract more than anything and has kept in contact with the company about his next move.AdvertisementAdvertisementAdvertisement”I talked with Hunter and [my manager] Tiki [Ghosn] yesterday. I told them, ‘I’m a chaos agent. I’m a very conflicted guy. I want the beef, I want the confrontation, so don’t tread on me, please,'” Costa said.”I’m here to win, like we’re at a poker table. I like to try my luck — to gamble. I’m a gambler. And I appreciate Dana White. Dana White doesn’t take care of [UFC matchmaking] business anymore. I don’t know what he’s doing right now,
