5 Reasons To Watch ONE Friday Fights 137: Tawanchai Vs. Liu On December 19
ONE Friday Fights 137: Tawanchai vs. Liu delivers the promotion’s final spectacle of 2025 this Friday, December 19, live in Asia primetime from Bangkok’s legendary Lumpinee Stadium.
The year-ending showcase features 12 explosive bouts where World Champions and title contenders collide with rising stars across multiple weight classes.
Each kickboxer and Muay Thai competitor will step into the ring with different goals.
Some athletes are eager to take another step toward their World Title ambitions, while others have a chance to secure a life-changing six-figure contract and global roster spot with the world’s largest martial arts organization.
With that in mind, ONE Championship’s final event of 2025 is something fans can’t miss. Here are five reasons why ONE Friday Fights 137: Tawanchai vs. Liu demands your attention.
#1 Tawanchai’s Kickboxing Redemption Begins
ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai seeks to revive his two-sport ambitions in the main event against Chinese upset king “Spirit Dragon” Liu Mengyang.
The sting of his shocking third-round TKO loss to former ONE Interim Featherweight Kickboxing World Champion Masaaki Noiri at ONE 172 this past March still lingers.
Not only did it mark the first time the Thai was finished in his promotional campaign, but it also prevented him from claiming the interim gold.
However, it didn’t deter Tawanchai from his mission. In fact, it made him even more motivated to prove he is the best 155-pound striker on the planet, and the featherweight Muay Thai king has already proven that his skills translate seamlessly under kickboxing rules with victories over Davit Kiria and “Smokin” Jo Nattawut.
With the burning desire to prove his doubters wrong, the 26-year-old faces a dangerous challenger who has already toppled some of the sport’s brightest superstars.
Liu defeated Noiri by unanimous decision in his promotional debut last December, announcing himself as a legitimate divisional threat.
Most recently, the Chinese standout overwhelmed Shadow Singha Mawynn at ONE Friday Fights 126 this past September, dropping the decorated Thai in round two en route to a unanimous decision.
For Tawanchai to successfully reignite his journey toward undisputed ONE Featherweight Kickboxing World Champion Superbon, it starts with Liu.
#2 Jaosuayai Looks To Make Statement In New Weight Class
Jaosuayai Mor Krungthepthonburi ventures into uncharted territory as he drops from flyweight to strawweight, where he seeks to attain the biggest win of his career.
The 24-year-old Thai knockout artist faces an immediate baptism by fire against living legend Sam-A Gaiyanghadao, the former two-sport, two-division ONE World Champion who remains one of the promotion’s most dangerous strikers.
Jaosuayai built his reputation on the ONE Friday Fights circuit, compiling an impressive run that earned him a life-changing six-figure contract in March. He continued proving his elite status after joining the organization’s global roster, stunning Nakrob Fairtex with a 52-second knockout at ONE Fight Night 32.
However, he stumbled in his last outing when his much bigger opponent, Akif “King” Guluzada, outpointed him via unanimous decision at ONE Fight Night 36, snapping a five-bout winning streak.
That setback forced Jaosuayai to discover whether his exceptional speed, power, and precision would be more amplified at a lower weight class.
Meanwhile, ONE Strawweight Muay Thai World Champion Prajanchai PK Saenchai is expected to defend his crown against Aliff Sor Dechapan next. A victory over Sam-A should position Jaosuayai as a legitimate threat in the World Title picture.
#3 Former World Champs & Contenders Ready To Make A Run
Three decorated veterans will face hungry challengers who are eager to make their names.
Former ONE Strawweight Muay Thai & Kickboxing World Champion Sam-A hopes to give Jaosuayai a rude welcome to the 125-pound division.
At age 42, the Thai legend has made a career out of beating younger contenders.
Sam-A snapped Thway Lin Htet‘s four-bout winning streak at ONE Friday Fights 126, proving age is merely a number. Beating Jaosuayai could set him on the path for another World Title run and further cement his legendary status.
Meanwhile, Nattawut goes head-to-head with young hungry lion Mohammad Siasarani in featherweight Muay Thai action. At his best, the Thai powerhouse is a well-rounded striker who pushes forward with relentless pressure and suffocating volume.
However, the former World Title challenger’s back is against the wall after a three-bout losing skid, making victory essential to prove he remains a force in the division.
Lower on the card, “Fighting Rooster” Zhang Peimian battles Thongpoon PK Saenchai in strawweight kickboxing. The 22-year-old Chinese star possesses frightening hand speed and footwork that earned him four promotional victories, including his win over Aliff Sor Dechapan.
But Zhang seeks redemption after recently stumbling with a pair of setbacks. If the Chinese star can rediscover his old form, he could put himself back in the conversation for a rematch with undisputed ONE Strawweight Kickboxing World Champion Jonathan Di Bella.
#4 Fan Favorites Seek Life-Changing Contracts
Several fighters sit on the cusp of earning six-figure contracts and global roster spots with the world’s largest martial arts organization.
In the co-main event, “Left Meteorite” Kulabdam Sor Jor Piek Uthai seeks to earn his way back to the main roster against fellow Thai veteran PTT Apichart Farm in a bantamweight Muay Thai tilt.
The two-time Lumpinee Stadium Muay Thai World Champion brings devastating one-punch knockout power to the table and rides a four-bout winning streak, which includes victories over John “Hands of Stone” Lineker and Felipe “Demolition Man” Lobo.
In another bantamweight Muay Thai clash, Yod-IQ Or Pimolsri meets Russian powerhouse Elbrus “The Samurai” Osmanov.
Yod-IQ has been on a tear, winning 10 of his 11 promotional matches while riding an eight-bout winning streak. His latest conquest was a surgical unanimous decision over Alessio Malatesta.
But Osmanov enters with his own impressive 8-1 promotional run, his lone setback coming against Yuki Yoza. Consecutive wins over Saemapetch Fairtex and Kampeetewada Sitthikul show that he’s applied the lessons learned from that defeat.
Elsewhere, Japanese standout Shimon Yoshinari battles Thai veteran Dedduanglek TDed99 in flyweight Muay Thai action.
The 21-year-old has raced to three straight promotional victories with whirling speed and relentless aggression.
Shimon seeks another emphatic performance after an unfortunate no contest against “Samingpri” Tagir Khalilov at ONE Friday Fights 134 last month.
#5 ONE Championship’s Final Show Of 2025
