Lee came up short in a controversial decision loss to Ok Rae Yoon in 2021, but the 23-year-old has been promised an immediate rematch by One Championship president Chatri Sityodtong.
Considering the high-level skillset Lee is already employing at such a young age, he seems destined to only improve from this point onwards. He would undoubtedly give much of the UFC's 170lb division trouble should he ever be given the opportunity to test himself against them.
#1. Reinier 'The Dutch Knight' de Ridder - One Championship middleweight & light heavyweight
One Championship's only current double champ Reinier de Ridder is another fighter to have taken the Singaporean promotion by storm over the past few years.
Currently holding a perfect 14-0 record, de Ridder has put together five consecutive wins in the One Championship Circle.
Reinier de Ridder defeated Aung La N Sung twice to claim both his titles, and now appears to be running out of high level opposition to test himself. Wins over Rong Fan, Gilberto Galvao and Leandro Ataides have helped round out his One Championship resume.
Considering the UFC's middleweight and light heavyweight divisions are somewhat lacking in depth and upcoming talent, de Ridder could easily enter either weight class and put on fun bouts.
'The Dutch Knight' yet to lose a pro MMA bout, it would certainly be intriguing to see just how high his ceiling is inside the world's largest MMA promotion.
