‘Discipline Beats Talent’ – Decho And Rustam Yunusov Put Six-Figure Dreams On The Line In ONE Friday Fights 155 Main Event
Two of flyweight Muay Thai’s most exciting young guns collide when surging Thai contender Decho Mavinn Muaythai and Russian teenage prodigy Rustam “Tomahawk” Yunusov meet in the main event of ONE Friday Fights 155 live in Asia primetime.
The card follows The Inner Circle on May 22, capping a stacked night of world-class martial arts action inside the historic Lumpinee Stadium in Bangkok, Thailand.
Both men are rising forces in the 135-pound striking division, and a life-changing six-figure contract could be within reach for whoever comes out on top.
Decho Targets Knockout Statement Against Undefeated Prodigy
Decho Singha Mavinn is hitting his stride at exactly the right time. The 23-year-old has built a 5-1 promotional record that tells the story of a fighter who has grown with every appearance.
After going the distance in his first five bouts, the Songkhla native finally flashed his finishing instincts at ONE Friday Fights 147, putting Elvin “Jaguar” Kazumovi to sleep with a sensational first-round knockout.
The statement’s finish suggested a warrior who is only getting more dangerous with time.
He said:
“I was really happy with my performance in my last fight because everything went exactly to plan. The strategy was to close the distance and damage him with my knees. That elbow to finish the fight was a weapon we specifically prepared for inside the clinch.”
The road gets tougher from here. Next up is a 19-year-old Russian phenom who has yet to taste defeat across 16 professional bouts.
Decho respects the threat and has a precise read on what makes his opponent dangerous.
The Thai clinch specialist said:
“Rustam is a southpaw with incredible footwork. He’s quick in and out, which is typical for Russian fighters, and his left hand and left kick are very sharp and fast.
“If I let him stay on the outside and fight at his own distance like his past fights, it’s going to be a tough night for me. I must close the distance and get on the inside.”
Decho has faced heavy hitters throughout his career, and those wars have forged an iron chin and a durability that few at this level can match.
He respects Yunusov’s striking but believes the Russian’s attacks are built on flash rather than finishing instinct. Win number 51 feels close, and he knows exactly what it could unlock.
The Mavinn Muaythai representative declared:
“As for his power, I’m not worried at all. He doesn’t really have that one-shot knockout power. Plus, I’ve already survived Suriyanlek’s ‘wild buffalo punches’, so there’s really no reason for me to fear anyone else’s weapons anymore.
“I’m confident that if I get past Rustam, that six-figure ONE Championship contract will be well within my reach.”

Yunusov Eyes Eighth Straight Win In First Main Event
Rustam Yunusov is a prodigy in every sense. The Moscow-born southpaw has gone 16-0 across his career, with his last seven victories forged against the sharpest competition on the weekly platform.
At 19, he has outclassed fighters with far more mileage on the clock, combining explosive power with a ring IQ that takes most fighters years to develop. None of it, he insists, came naturally.
He said:
“I can say I’m not such a talented person, especially in Muay Thai. My only talent is my discipline. Discipline beats talent.”
Heading into his first main event, the teenage wonder faces the most significant test of his young career against a savvy Thai combatant.
Yunusov is well aware that Decho is a battle-tested veteran who has navigated the weekly crucible with consistency and poise.
He approaches this showdown with a deep respect for the traditional weapons that make his adversary such a credible threat.
“Tomahawk” said:
“Decho is a pretty experienced one. He’s young, but he has a lot of professional fights. And he’s a pretty smart fighter.
“He fights like a tank — just go straight and make a kill. He has good fighting IQ and good clinching skills. So it’s a real challenge for me.”
That admiration evaporates the moment the bell rings. Yunusov is a true student of the game, dissecting opponents down to their smallest tendencies before he ever sets foot in the ring.
The Russian already mapped out how Decho operates, and he has a clear answer for every weapon in his arsenal.
He concluded:
“I can say he has a pretty simple Thai style. But he can use it differently. He has a good fighting IQ. He will fight with me like a Thai guy, but he will make some [feints], and he will be faster in the clinch. I feel he will try to make me tired with his fakes.
“I don’t think [he can keep up with me]. Because I have a better tactic and my fighting IQ is higher than his.”
