Usman lost to Chimaev by majority decision last October at UFC 294.
"Because of our fight, people started belittling Hamzat's qualities. Everyone says he's not that good. But actually I was the champion.... I think people are misjudging him. I think Hamzat is a serious problem for any opponent. Personally, he made me work up a sweat from the first round," Usman said on the YouTube channel Pound4Pound.
Recall that his next fight Chimaev will hold against Robert Whittaker. The fight will take place on June 22 in the main event of the debut UFC tournament in Saudi Arabia.
