Paulo Costa responded negatively to comments made by Azamat Murzakanov about a 'secret juice' possessed by Russian fighters. Murzakanov had stated that people will soon learn what the secret is that fighters from Russia have. The Brazilian middleweight appears to have taken offense at these remarks, though his specific response is not detailed in the post. The comments suggest potential tension building before their scheduled bout. Murzakanov's cryptic references to Russian fighters having a secret advantage seem designed to get under Costa's skin. The exchange adds another layer to the promotional buildup between the two middleweights.
