Moreno: "Demetrious Johnson is at least one of the top five fighters in history"

The legendary American announced his retirement from the sport this past weekend during the ONE 168 tournament at the Ball Arena in Denver.

"I actually had the opportunity to surprise with him a few weeks ago. We practiced together. He's an unbelievable person. Very cool and easy going. Demetrious is a legend in our sport. And he's at least one of the top 5 best fighters of all time. So I wish him all the best," Moreno is quoted as saying by BJ Penn.
