Paulo Costa has responded to recent comments made by Azamat Murzakanov about a "secret juice" or special advantage possessed by Russian fighters. Murzakanov stated that "very soon we will show what the secret is" and that people will "soon find out" what Russian fighters have that gives them an edge. The comment appears to have bothered Costa, who is scheduled to face Murzakanov soon. The nature of Costa's specific reaction was not detailed in the post, but the implication is that he took issue with Murzakanov's remarks.
