A Muay Thai legend and a multiple-time Lumpinee Stadium world champion, Sam-A Gaiyanghadao, 34, of Thailand is regarded as one of the best strikers in the world. On May 18, 2018, he will compete for the inaugural ONE Super Series Flyweight Muay Thai Championship against Sergio “Samurai” Wielzen, 30, of Suriname and the Netherlands at “ONE: Unstoppable Dreams.”

Gaiyanghadao made his ONE Championship debut on January 26, 2018 at “ONE: Global Superheroes” at the SM Mall of Asia Arena in Pasay City, Metro Manila, Philippines where he knocked out Joseph Lasiri, 26, of Italy in ONE Championship’s first ever Muay Thai match. Taking place at the Singapore Indoor Stadium in Kallang, Singapore, “ONE: Unstoppable Dreams” will mark Gaiyanghadao’s second bout in the promotion.

“Competing in front of a packed arena to an audience of millions around the world, it was such a surreal experience for me the first time I stepped into the ONE Championship cage,” Gaiyanghadao recalled. “I can still remember the feeling like it was yesterday. Thank you ONE Championship for the opportunity to compete for the world title, I am truly honored and will make everyone proud.”

As a Muay Thai practitioner, Gaiyanghadao owns a record of 364-46-9 and was known for his strong defense and counter offense. The Muay Thai legend is also an instructor at Evolve MMA in Singapore.

“ONE: Unstoppable Dreams” will mark Wielzen’s ONE Championship debut. His upcoming bout against Gaiyanghadao is one of the two co-main events of “ONE: Unstoppable Dreams.”

On May 14, 2018, Gaiyanghadao and Wielzen attended the press conference for “ONE: Unstoppable Dreams” at the Marina Bay Sands in Bayfront Subzone, Downtown Core, Singapore. Also present during the event were reigning ONE Women’s Atomweight World Champion “Unstoppable” Angela Lee, 21, Mei “V.V” Yamaguchi, 35, reigning ONE Featherweight and Lightweight World Champion Martin “The Situ-Asian” Nguyen, 29, Christian “The Warrior” Lee, 19, Yodsanklai “The Boxing Computer” Fairtex, 32, and ONE Championship chairman and CEO Chatri Sityodtong, 47.
