WBA bantamweight champion Rigondeaux has warned Bob Arum and the rest of the boxing world that he will emerge victorious against Vasyl Lomachenko.
Rigondeaux will take on Lomachenko for the Ukrainian's WBO junior lightweight title at New York's Madison Square Garden on 9 December.
It is one of the most highly anticipated match-ups in recent boxing history as it is a rare battle between two Olympians who have won two gold medals each and have both dominated during their amateur days.
Rigondeaux will be moving up eight pounds and two weight divisions for the bout as the winner of this contest will no doubt, stake a claim for the pound-for-pound top spot.
The size advantage for "Hi Tech", however, has led many to believe that Rigondeaux will be on the losing end.
Former flyweight boxing champion Rosendo Alvarez claimed earlier this month that "El Chacal" will not have the same power or speed against Lomachenko while Lomachenko himself is prepared to receive his critics if he defeats the smaller man.
Rigondeaux though, says he will be delivering a massive blow to Top Rank promoter Bob Arum for matching his fighter up with him, adding that the size advantage has been overblown.
"It's going to be a tremendous blow, I do not know how [Bob Arum] let Lomachenko face me, he thinks Lomachenko can beat me," Rigondeaux said, as quoted on BoxingScene. "But he's made a huge mistake, he does not know that he's going down like Nonito too.
"I tell you that we are even [physically]. For the time being it is a secret, but let them see the day of the weigh-in. People will be surprised, I have not paid so much attention to these physical issues, it is my responsibility to prepare my skills and in that respect I am superior."
The unbeaten Cuban also claimed that no other boxer will want to face him once he shocks the world with a win over Lomachenko.
"There is no other fighter on this planet who is looking for fights and people are running away," he added. "And if by beating Nonito everyone got scared, imagine what can happen when I beat Lomachenko.
"Names don't mean anything anymore and prizes mean nothing over what happens in the ring. On December 9 we will see who speaks the most and when I beat Lomachenko - let's see what [the critics] invent then, because everything happens to me."
