In the fast-paced world of men’s doubles badminton, where partnerships are often tested by pressure, personality, and performance, few stories captivate fans quite like the incredible journey of Malaysia’s Goh Sze Fei and Nur Izzuddin Rumsani. From humble beginnings, public separation, and reconciliation, to finally clinching the coveted World No. 1 spot, their story is nothing short of inspirational. But for Sze Fei and Izzuddin, reaching the summit is just the beginning—the real mission lies in staying there.
The Origins of a Promising Pair
The tale begins in Melaka and Johor, the respective hometowns of Sze Fei and Izzuddin. Both were born in the late 1990s and entered the national badminton setup as teenagers. It wasn’t until 2016 that they were officially paired by the Badminton Association of Malaysia (BAM), forming a partnership that, while unassuming at first, would eventually evolve into one of the strongest in the global men’s doubles scene.
Their chemistry wasn’t instantaneous. Unlike some explosive pairings that click from the first tournament, Sze Fei and Izzuddin took time to develop their rhythm. But what they lacked in early finesse, they made up for in grit, work ethic, and mutual respect.
By 2019, they were regular fixtures at international tournaments. Their breakthrough moment came in 2022, when they captured the German Open title, beating some of the sport’s biggest names along the way.
Split Struggles and Second Chances
In early 2023, the Malaysian badminton world was stunned when BAM announced that the pair would go their separate ways. The official reason cited was the need to try new combinations, but insiders spoke of frustration, fatigue, and differing playing philosophies between the two.
The separation was short-lived.
Within six months, both players found themselves struggling with new partners. Their ranking tumbled, performances plateaued, and confidence waned. More importantly, fans noticed a lack of spark, that special something that had once made Sze Fei and Izzuddin a force to be reckoned with.
By mid-2023, under mounting public pressure and after honest conversations between themselves, the pair decided to reunite—older, wiser, and more determined.
“We had to fall apart to understand how strong we are together,” said Izzuddin in a press conference following their return.
The Climb to Number One
The reunion sparked a resurgence.
Under the tutelage of coach Rexy Mainaky, the pair sharpened their tactical play and refined their shot selection. Gone was the erratic play that had once cost them crucial matches. In its place: mature defense, explosive counter-attacks, and seamless transitions.
The latter half of 2023 saw them reach the finals of the Thailand Open, semifinals of the Japan Open, and quarterfinals in the World Championships. They closed the year by clinching the Malaysia Masters title, a fitting triumph on home soil.
In early 2025, after a stellar run including victories over several top-ranked pairs and back-to-back Super 500 finals, the unthinkable happened: Sze Fei and Izzuddin were officially ranked No. 1 in the BWF Men’s Doubles rankings.
It was a historic moment—not just for them, but for Malaysia. They became the first all-Malaysian men’s doubles pair in nearly a decade to occupy the top spot.
Reactions to the Milestone
The badminton world responded with admiration and applause.
Former Malaysian great Koo Kien Keat called it “a moment of redemption and an example of what persistence can achieve.” Social media exploded with celebratory messages, with hashtags like #SzeFeiIzzuddinNo1 trending on Malaysian Twitter.
But perhaps the most poignant reaction came from the players themselves.
“This ranking is not a trophy—it’s a responsibility,” said Sze Fei in an interview with Astro Arena. “We are proud, but we are not satisfied.”
“We’ve worked too hard to be a one-hit wonder,” added Izzuddin. “This is where the real test begins.”
Challenges That Lie Ahead
If reaching the top is difficult, staying there is even harder.
The men’s doubles category is arguably the most competitive field in badminton today, featuring elite pairs like Indonesia’s Fajar Alfian/Muhammad Rian Ardianto, China’s Liang Wei Keng/Wang Chang, Japan’s Takuro Hoki/Yugo Kobayashi, and Korea’s Kang Min Hyuk/Seo Seung Jae.
Each of these pairs possesses unique playing styles and strategies. The margin of error at the highest level is razor-thin.
For Sze Fei and Izzuddin, maintaining their position will require:
- Physical consistency: Their playing style is high-energy, relying on quick reflexes and sharp net exchanges. Injury prevention and recovery will be critical.
- Mental resilience: As World No. 1s, every opponent now sees them as the pair to beat. The mental pressure in each match will be unlike anything they’ve faced before.
- Adaptability: The game evolves rapidly. New tactics, formations, and deceptive plays are emerging constantly. Staying ahead of the curve tactically will be crucial.
A New Approach to Greatness
Aware of the challenges, the pair has adopted a more holistic approach to their training and preparation.
They now have a dedicated sports psychologist to help manage pressure situations. Recovery protocols have been enhanced with cold therapy, physiotherapy, and monitored sleep cycles. Nutritional regimens have been customized to fit their metabolic needs, helping them maintain peak performance over longer stretches of the season.
Moreover, they’ve begun studying analytics—using performance data to identify trends, patterns, and weaknesses in their play and in that of their opponents.
“We are not the same players we were two years ago,” said Izzuddin. “We now understand that greatness is not just about power and speed—it’s about sustainability and growth.”
Olympic Dreams and Legacy Goals
With Paris 2026 on the horizon, the ultimate dream for Sze Fei and Izzuddin is an Olympic medal.
Malaysia has never won Olympic gold in badminton, though they’ve come heartbreakingly close. For this pair, the Olympics represent more than just a competition—it’s the stage to etch their names into history.
But they’re not stopping there. In multiple interviews, the duo has mentioned long-term goals:
- Becoming multiple-time Super Series champions
- Winning the World Championships
- Inspiring the next generation of Malaysian shuttlers
To that end, they’ve begun mentoring younger players in the national setup and participating in grassroots events, sharing insights, and creating opportunities for aspiring athletes.
The Fans The Fuel
Much of Sze Fei and Izzuddin’s success is rooted in their connection to the fans.
Whether it’s autograph sessions after matches, interactive livestreams, or candid behind-the-scenes footage, they’ve cultivated a reputation for being approachable and genuine. This authenticity has earned them not just admiration, but loyalty.
During the final of the Malaysia Masters, chants of “Sze Fei! Izzuddin!” echoed through the Axiata Arena. Flags were waved, banners displayed, and tears shed—testament to how much their journey means to the nation.
As one fan put it:
“They’re not just champions on court. They’re champions of the people.”
Defining Greatness
So what does greatness mean for Sze Fei and Izzuddin?
Is it about rankings? Trophies? Medals?
Yes—and no.
For them, greatness is about evolution. It’s about learning from losses, embracing vulnerability, and striving to improve every single day. It’s about taking criticism constructively, dealing with fame humbly, and playing not just for themselves—but for a flag, a community, a dream.
It’s about writing a legacy, one point, one match, one tournament at a time.
