George Jarvis Explains His Tactical Masterplan Against Regian Eersel

Will that be enough to dethrone “The Immortal”? That remains to be seen. But one thing is certain—Jarvis isn’t just showing up. He’s showing out.

George Jarvis Plots Tactical Upset Against Regian Eersel at ONE Fight Night 34

When George Jarvis steps into the iconic Lumpinee Boxing Stadium on August 1 for ONE Fight Night 34, he won’t be looking to win a war of attrition.¹

Instead, the British Muay Thai standout will bring a cerebral, strategic approach against one of the sport’s most dominant champions—Regian Eersel.

As the Englishman eyes the ONE Lightweight Muay Thai World Title, his preparation centers not on brute strength, but on tactical precision and leveraging a diverse arsenal of weapons.

This high-stakes showdown promises a fascinating clash of styles: Eersel’s methodical yet explosive striking vs. Jarvis’ brain-over-brawn blueprint. Below, we break down the layers of Jarvis’ mindset, tactics, and what this fight could mean for the future of the division.

A New Breed of British Striker

George Jarvis is part of a wave of UK fighters redefining what it means to be a top-level striker. Based out of Lumpini Crawley, Jarvis has built a reputation not merely for his power or aggression, but for a highly refined technical game.

His journey from local circuits in the UK to headlining at one of Muay Thai’s most sacred arenas is a testament to his evolving skill set and strategic growth.

Where traditional British Muay Thai fighters have historically relied heavily on forward pressure and durability, Jarvis has carved a niche for himself with calculated offense and an emphasis on ring IQ. It’s this precise and measured style he believes will be key to overcoming Eersel’s dominance.

The Regian Eersel Problem

To understand the magnitude of the task ahead of Jarvis, one must look at the man he’s facing. Regian “The Immortal” Eersel is a two-sport ONE World Champion—reigning in both kickboxing and Muay Thai at lightweight.

His résumé is filled with highlight-reel finishes, dominant decisions, and a streak of invincibility that has left most challengers scratching their heads.

Eersel’s game is rooted in a relentless pressure style, high-volume combinations, and masterful control of distance.

His ability to absorb damage while returning fire with surgical precision has made him one of the most feared strikers on the planet.

But Jarvis isn’t walking into this bout blind. In fact, he’s one of the few fighters who openly acknowledges the futility of engaging Eersel in a pure slugfest.

George Jarvis’ Tactical Declaration

“Why Stand and Trade?” 

In a candid interview with the South China Morning Post, Jarvis pulled back the curtain on his game plan—just a little.²

He was adamant that matching Eersel in a head-on striking war would be a fool’s errand.

“You know, I’m not going to go into too much detail,” Jarvis said, “but why am I going to stand and trade with someone who wins the majority of his fights doing that?”

The logic is sound. If Eersel thrives in chaotic exchanges, then dragging him into unfamiliar territory could be Jarvis’ best bet.

That could mean engaging from the outside, mixing in clinch work, or utilizing evasive footwork to disrupt Eersel’s rhythm.

“And you know, when I’ve got all this other skill set to take him out, why am I going to go down to having a slugfest with someone who I can beat in different ways, if that makes sense?” he added.

Studying the Champion: Jarvis’ Strategic Homework

Fighters who have challenged Eersel often prepare for his pressure with brute conditioning or matching him punch-for-punch.

Jarvis’ approach is fundamentally different. He’s reportedly been deep in film study, analyzing the subtle holes in Eersel’s transitions between kickboxing and Muay Thai.

Though Eersel has looked nearly untouchable, his fight with Sinsamut Klinmee revealed a brief vulnerability.

Sinsamut’s counter-punching and patience in the early rounds slowed the champion’s tempo. While Eersel eventually secured victory, the fight offered Jarvis clues on where to attack.

Expect Jarvis to focus on angles, distance management, and exploiting Eersel’s occasional tendency to square up when resetting.

Tactics Over Emotion: Staying Cool in the Heat

Another key component of Jarvis’ game plan is emotional control. He’s not entering the Lumpinee Stadium to prove how tough he is—he’s coming to win.

Fighters who let ego dictate their decisions against Eersel often get lured into firefights they can’t win.

Jarvis is adamant that remaining calm under pressure will be as vital as any physical preparation.

“It’s about intelligence, not emotion. I can brawl if I need to, but the goal isn’t to play his game. The goal is to make him play mine,” he hinted in a recent gym-side interview.

George Jarvis: The Muay Thai Mind

Building a Versatile Arsenal

Jarvis’ confidence in his diverse skill set isn’t unfounded. His development under elite Muay Thai coaches has allowed him to evolve into a multifaceted fighter capable of fighting on the front foot or backpedaling and countering.³

From sharp elbows to sneaky sweeps, from checking kicks to framing in the clinch, Jarvis has shown the ability to adapt mid-fight.

Against someone like Eersel—who thrives on predictability and rhythm—that adaptability could be the X-factor.

The Mental Edge: Embracing the Underdog Role

• One of Jarvis’ biggest advantages may be psychological.
• With Eersel considered nearly unbeatable, the pressure is squarely on the champion. Jarvis, on the other hand, enters the ring as a hungry underdog with everything to gain and little to lose.
• He’s already embraced that narrative, stating, “Everyone sees Regian as the final boss. I see him as a puzzle to solve.”
• That mindset allows Jarvis to approach the fight with clarity, without the burden of expectation that often crushes other contenders.
• Should Jarvis pull off the upset, the ramifications will be seismic.
• Not only would it end one of the most dominant reigns in modern Muay Thai, but it would also catapult the Brit into global stardom.
• It could also inject new life into a division that has been locked down by Eersel’s reign of terror.
• A new champion always brings new challengers, fresh storylines, and renewed excitement to the sport.

George Jarvis Ready for War

Why He’s Willing to Trade Leather with Regian Eersel

When George Jarvis steps into the ring against Regian Eersel at ONE Fight Night 34, he’ll be doing so with a firm plan in mind—stick to his strengths and avoid a wild brawl.

The 24-year-old British phenom has shown maturity beyond his years throughout his run in ONE Championship, and facing a seasoned champion like Eersel, he knows that brains might beat brawn.

“I’d rather play it smart,” Jarvis told the South China Morning Post. “But if it turns into a firefight, then so be it. Chin down, we get to work.”

That single sentence defines Jarvis’ mentality going into this high-stakes Muay Thai contest: be tactical, be smart—but be ready for hell if needed.

The Mecca of Muay Thai: Lumpinee Stadium Awaits

The venue itself adds weight to the moment. Lumpinee Stadium in Bangkok, Thailand, isn’t just a ring—it’s a symbol.

A temple of war for generations of elite strikers. Fighting there is a dream for many, but for Jarvis, it’s also a proving ground.

Facing Eersel at the Mecca of Muay Thai elevates the challenge.

The Dutch-Surinamese striker is no ordinary champion—he’s held the ONE Lightweight Muay Thai World Title since 2022 and is widely regarded as one of the most versatile and devastating strikers on the planet.

Eersel’s Aura: The Shadow Over the Division

Regian Eersel, nicknamed “The Immortal,” has carved out an intimidating reputation with his brutal efficiency inside the Circle.

Holding both the lightweight kickboxing and Muay Thai world titles in ONE Championship, he brings an unrelenting pace, intelligent angles, and the kind of composure only a seasoned veteran can exude.

For George Jarvis, Eersel’s aura is not a deterrent—but a motivator.

“I’m not walking in scared of him,” Jarvis said. “I respect what he’s done, but I’ve got something to prove, and I’m not just here to make up the numbers.”

The Climb: From Split Decision Loss to Four-Fight Win Streak

Jarvis’ rise hasn’t been linear. His ONE debut ended in a razor-thin split decision loss, but it was also a valuable learning experience.

Since then, the Brit has gone on a tear—racking up victories over Mustafa Al Tekreeti, Ricardo Bravo, Rungrawee Sitsongpeenong, and Mouhcine Chafi.

Each win showcased a different layer of his game: crisp elbows, solid clinch work, evasive footwork, and an ability to adapt mid-fight. Most importantly, Jarvis has developed the fight IQ that could be his X-factor against someone like Eersel.

George Jarvis’ Training Camp: Sharpening the Arsenal

Leading into this fight, Jarvis has been putting himself through a grueling camp.

Word from his camp is that he’s been focusing heavily on defensive movement, body conditioning, and counterattacks—all essential tools to deal with an aggressive, high-volume striker like Eersel.

He’s also reportedly brought in southpaw sparring partners to mimic Eersel’s stance and cadence, as well as former world champions to challenge his mental toughness. The message is clear: he’s not leaving any stone unturned.

A Win Here Changes Everything

At just 24, George Jarvis has the opportunity to shock the world. A victory over a legend like Eersel would catapult him into superstardom and potentially open doors to crossover bouts in kickboxing or even MMA.

More than that, it would affirm what Jarvis has believed all along—that he belongs at the top, not just as a competitor, but as a champion.

The Intangibles: Youth, Hunger, and Nothing to Lose

There’s something about being the underdog that allows fighters to swing freely. Jarvis knows the odds are stacked against him. He knows Eersel has defended his titles against elite competition time and time again.

But he also knows that youth, hunger, and absolutely nothing to lose can be dangerous. He’s entering with a clear mind, a sharp game plan, and the humility to adapt.

“I’m not trying to be anyone else,” Jarvis said. “I’m trying to be the best version of me. If that means going through fire to win, then so be it.”
