Brazilian superstar Adriano Moraes is one of the most dominant world champions in the history of ONE Championship. His record of eight world title bout wins is only second to Bibiano Fernandes (11), and his three world championship reigns over the eight-year history of the belt are proof of his mastery over his peers in the division.At ONE on Prime Video 1, he will face the toughest test of his professional career as he goes up against Demetrious Johnson for a second time. The event will be broadcast live at U.S. primetime on August 26.While Moraes already owns a piece of history by becoming the first man to knock out ‘Mighty Mouse’ in MMA, their second tilt will prove to be an even tougher test for ‘Mikinho’. Johnson, considered by many to be one of the best fighters of his generation, will no doubt come out with a renewed passion to prove that he is still in his prime by redeeming himself from his latest MMA loss.However, if there's one man who has the ability to hand Johnson the first back-to-back losses of his MMA career, it has to be Moraes. Here are five reasons why Adriano Moraes will beat Demetrious Johnson at ONE on Prime Video 1.#5.

Add the fact that Moraes is in perpetual motion when he fights, and it looks almost impossible for Johnson to land a clean shot on his rival if they stay on their feet.Should they go on the ground, the long limbs of 'Mikinho' will only amplify his already formidable Brazilian jiu-jitsu skills, whether to defend or to inflict damage.
