The Inner Circle returns to Lumpinee Stadium in Bangkok, Thailand, on Friday, May 15, and it brings one of the most stacked lineups in the series’ history. This is one night martial arts fans cannot afford to miss, airing live in Asia primetime at live.onefc.com. 

The most highly anticipated rematch in recent memory headlines the night, as ONE Heavyweight MMA World Champion “Reug Reug” Oumar Kane defends his belt for the first time against the man he dethroned, two-division ONE MMA World Champion Anatoly “Sladkiy” Malykhin. 

The high-stakes card also features the return of ONE Lightweight Submission Grappling World Champion Kade Ruotolo. Elsewhere, redemption awaits for reigning ONE Flyweight Kickboxing World Champion “The Kicking Machine” Superlek and Abdulla “Smash Boy” Dayakaev.

With championship gold and personal pride on the line, here are five burning questions surrounding Friday’s massive event.

#1 Will ‘Reug Reug’ Beat Malykhin For The Second Time?

When “Reug Reug” and Malykhin met at ONE 169 in November 2024, they produced one of the greatest heavyweight battles in recent memory. The two pushed each other to the limit across five grueling rounds. When the dust settled, it was Kane who walked away with the split decision and 26 pounds of gold.

What made it remarkable was who he beat. Malykhin entered with a perfect 14-0 slate and a 100 percent finishing rate. Yet Kane silenced every doubter, put Senegal on the global combat sports map, and proved the nation’s traditional wrestling belonged at the highest level. Upon his return home, over 20,000 fans greeted him as a hero in Dakar. 

Now, he arrives at the rematch carrying a different burden. No longer the underdog, Kane sets his sights on a finish that leaves no room for debate and cements him as the world’s premier heavyweight. 

#2 Can Malykhin Reclaim His Three-Division World Champion Status?

Malykhin had achieved what no fighter in MMA history had. The Russian juggernaut conquered the middleweight, light heavyweight, and heavyweight divisions to stand as the sport’s first and only three-division MMA World Champion. 

Then came the split-decision loss, the first and only blemish on an otherwise perfect record. He recovered from injury in the months that followed, only for Kane’s car accident to postpone the highly anticipated rematch at ONE 173 last November.

That defeat lingered for over a year, but Malykhin never stopped working. He channeled the frustration, sharpened his weapons, and is headed to Bangkok with purpose — to finish Kane, reclaim the belt, and prove one loss does not define what he built across three divisions. 

#3 Can Ruotolo Pick Up Where He Left Off After A Year On The Sidelines?

Ruotolo has achieved everything the grappling world has to offer. He defended his ONE Lightweight Submission Grappling World Title three times and established himself as one of the finest grapplers of his generation. When he made the leap to MMA, three first-round stoppages proved his skills translated seamlessly to the all-encompassing sport. 

Then the injury bug intervened. Ruotolo suffered a complete ACL tear just one week after submitting Nicolas “El Paisa” Vigna at ONE 171. During his recovery, he watched his twin brother and fellow ONE World Champion Tye Ruotolo flourish on his own MMA journey, every triumph only fueling his desire to return. 

Now healthy, he faces a legitimate test in hard-hitting Hiroyuki “Japanese Beast” Tetsuka. Another statement win would keep his undefeated record across both MMA and grappling intact and put him firmly on a collision course with two-division MMA World Champion Christian “The Warrior” Lee. 

#4 Can Superlek Silence His Critics With A Statement Win?

Not long ago, Superlek stood among the finest pound-for-pound strikers on the planet. Having defeated some of the biggest names in the promotion, he had cemented his status as a modern great and looked settled at the top of the striking world. 

Then 2025 arrived and tested everything. He lost his ONE Bantamweight Muay Thai World Title on the scales, then suffered back-to-back losses to Nabil Anane and Yuki Yoza in performances that had critics questioning whether his best days were behind him.

Instead of listening to the noise, he went back to work. He returned to YOKKAO Training Center in Bangkok to reconnect with his roots and rebuild not just his skills but his mindset. Now the familiar canvas of Lumpinee Stadium serves as his stage, and a win over the dangerous Dayakaev would be the loudest possible answer to anyone who wrote him off. 

#5 Will Dayakaev Seize His Biggest Opportunity Yet?

Dayakaev built his reputation on destruction, with multiple sub-minute knockouts establishing the Russian as one of the most feared finishers in the bantamweight Muay Thai division.

That trajectory was derailed at ONE Fight Night 39 when Rambolek Chor Ajalaboon stopped him cold. What followed only deepened the pain. The Thai star walked straight into a ONE World Title shot and claimed the ONE Bantamweight Muay Thai World Championship in his very next fight, a moment that could have been Dayakaev’s. 

Now, “Smash Boy” arrives with a point to prove, and Superlek presents the perfect opportunity.  A victory over the pound-for-pound icon would be the defining win of his career and perhaps the clearest path back to a rematch with Rambolek.

Wherever Abdulla “Smash Boy” Dayakaev goes, destruction inevitably follows. The Russian knockout artist will make his highly anticipated return at The Inner Circle on May 15 with everything to prove.

Dayakaev faces reigning ONE Flyweight Kickboxing World Champion “The Kicking Machine” Superlek in a three-round bantamweight Muay Thai showdown. The blockbuster event broadcasts live in Asia primetime from Bangkok’s legendary Lumpinee Stadium, exclusively on live.onefc.com.

Few fighters on the ONE Championship roster boast a more menacing resume. The Dagestan-born striker carries a staggering 75 percent finish rate across his 10 promotional appearances, with an average bout duration of under five minutes.

However, stopping Superlek will require a feat no opponent has managed in over 12 years. The Thai icon is globally renowned for his impregnable defense and an iron chin to match.

But if there is anyone capable of shattering Superlek’s aura of invincibility, it is a certified harbinger of doom like Dayakaev. Before these two striking titans share the ring, here are three reasons why “Smash Boy” possesses the perfect arsenal to knock out anyone standing in his way.

#1 Dayakaev Is Built To Stop Fights

Dayakaev is blessed with physical gifts, and he has spent every day in the gym ensuring his work ethic is worthy of them. 

At 5-foot-10, the Pattaya-trained finisher carries elite length for the bantamweight division and knows how to use every inch of it. Those longer limbs generate devastating rotational force, landing strikes before opponents even recognize the danger.

Then there is the foundation beneath it. Forged in the combat-hardened conditions of Dagestan, Dayakaev arrived in Muay Thai with sambo and wrestling already embedded in his body, translating directly into exceptional core strength and hips built for explosive torque. His knockout power is not merely stylistic, it is engineered. 

Superlek struggled badly against the length and range of former bantamweight Muay Thai king Nabil Anane, surrendering distance he could never reclaim. His teammate Dayakaev presents the same problem with considerably more firepower behind it. 

#2 Abdulla Dayakaev Hits Exactly Where It Counts

As fearsome as Dayakaev’s power is, it only tells half the story. Beneath the surface, the Team Mehdi Zatout standout possesses something far more dangerous — an underrated, almost surgical sense of timing. 

“Smash Boy” does not simply hit hard. He connects at the exact moment opponents are most exposed, throwing bombs mid-combination when the guard is in motion and the body has committed. Rather than wait for a sequence to end, he intercepts it. 

That pattern emerged when he dusted off Sibmuen “Coach Nay” in 35 seconds, then repeated itself in even more devastating fashion during his record-setting 24-second annihilation of Nontachai Jitmuangnon. Neither finish came from patient counter-striking, but from a single, perfect read. 

Superlek thrives on long, flowing combinations, and for most opponents, surviving them is the challenge. For Dayakaev, they are an invitation, and one clean window is all he needs. 

#3 Dayakaev Turns Attrition Into Annihilation 

While Dayakaev has proven he can end fights in an instant, the finish is never something he chases recklessly. His priority is damage accumulation, and by the time the knockout arrives, the opponent has long been outclassed.

Round by round, he chips away at structural integrity, slows reactions, and erodes defenses. The breakdown is systematic, making the finish inevitable. 

His come-from-behind TKO of Saemapetch Fairtex illustrated this best. After surviving a knockdown, Dayakaev recalibrated, invested in body shots, and wore the Thai veteran down until a window opened. Opponents do not simply lose to him — they deteriorate. 

At ONE 173, Superlek absorbed a unanimous decision loss to Yuki Yoza, who broke the Thai down with relentless, well-placed combinations to the head and body. Dayakaev brings the same style of calculated, compounding assault and the finishing instincts to close it out.
