Costa has found a new rival in the Russian-born Swedish fighter #khamzatchimaev ‘Borz’ and ‘Eraser’ previously crossed paths in the lead-up of UFC 279 at the Las Vegas PI. The two almost got into a physical brawl. But were separated by their teams. Since then, the Brazilian has been asking for a fight with the welterweight star. However, Chimaev never responded to the call-out, as he desires to continue competing at 170lbs, despite the previous weight miss. Even though #paulocosta always displays a funny persona on social media, this time he appeared serious as the UFC fighter posted a series of tweets regarding the same. ‘Borz’ is currently undefeated in the promotion and is looking for an opponent who can match his caliber. Thus, according to many reports, the organization is looking to finalize Chimaev vs. Covington next. Previously, Chimaev also uploaded a fan-made poster of the same. However, the UFC hasn’t announced the fight officially yet. Nonetheless, given their standings in the welterweight roster, this fight might surely happen next. Who do you have winning? #chimaevcosta
