Cristiano Ronaldo has never been reluctant to defend his place among football’s all-time greats. However, a resurfaced interview in which the Portuguese superstar declared himself the greatest footballer in history has reignited the long-running debate over who truly deserves the title.
A clip uploaded by CNN Portugal on Monday, October 12, went viral before being taken down, bringing Ronaldo’s bold assertion back into the spotlight. The renewed attention came days after the Portugal captain was suspended from the national team.
Ronaldo’s remarks were not new, but they once again raised a familiar question: should sporting legends declare themselves the greatest, or should that distinction be left to fans, critics and history?
“I’m the best in history. Full stop. There’s no debate about who the best in history is. You just have to keep scoring goals. The numbers say it all,” Ronaldo said in the interview.
The 41-year-old’s confidence reflects a career built on extraordinary goalscoring records, sustained excellence and success across some of Europe’s biggest clubs. Yet the debate remains complicated by Lionel Messi’s achievements, particularly Argentina’s 2022 FIFA World Cup triumph and his record eight Ballon d’Or awards.
The argument, however, extends beyond football. Across sporting history, some of the greatest athletes have openly proclaimed their own greatness, using confidence as a source of motivation, a competitive weapon or a defining part of their public identity.
Few mastered that art quite like boxing legend Muhammad Ali.
MUHAMMAD ALI: CONFIDENCE AS A PERFORMANCE
Long before social media made athletes’ statements instantly shareable, Muhammad Ali understood the power of a memorable declaration.
“I am the greatest!” became one of his defining catchphrases, reflecting a personality that was as compelling outside the boxing ring as it was inside it. Ali once went even further, declaring, “I’m not the greatest, I’m the double greatest.”
His words were backed by remarkable achievements. A three-time world heavyweight champion, Ali transformed boxing through his skill, charisma and psychological battles with opponents.
For Ali, proclaiming himself the best was not simply an expression of ego. It was part of his sporting persona, designed to command attention, unsettle opponents and build anticipation before a fight.
His confidence ultimately became inseparable from his legacy.
ZLATAN IBRAHIMOVIC: NO AWARD REQUIRED
Football has produced its own share of outspoken personalities, and Zlatan Ibrahimovic remains one of the most memorable.
In 2013, the Swedish striker declared, “I don’t need the Ballon d’Or to know I’m the best.”
The statement captured Ibrahimovic’s trademark swagger at a time when Lionel Messi, Cristiano Ronaldo and Franck Ribery dominated discussions surrounding individual football honours.
Ibrahimovic’s career offered plenty of reasons for his confidence. He won league titles across several European countries, scored spectacular goals and became one of the most recognisable forwards of his generation.
Although he never won the Ballon d’Or or the UEFA Champions League, he maintained an unwavering belief in his own abilities.
For Ibrahimovic, greatness was not something that depended entirely on trophies awarded by others.
LEBRON JAMES AND THE CASE FOR HIS OWN GREATNESS
Basketball superstar LeBron James has also been forthright about his place in sporting history.
In 2023, as he approached Kareem Abdul-Jabbar’s NBA career scoring record, James told the Orange County Register, “I feel like I’m the best basketball player that ever played the game.”
The declaration came after years of extraordinary achievements, including NBA championships, regular-season MVP awards and sustained excellence across multiple generations of players.
James surpassed Abdul-Jabbar’s regular-season scoring record in February 2023. In March 2025, he became the first player in NBA history to surpass 50,000 combined regular-season and playoff points.
Those milestones have strengthened his argument, although comparisons with Michael Jordan and other basketball legends continue to divide fans and analysts.
Like Ronaldo, James has never felt compelled to remain silent about where he believes he belongs in the sport’s history.
USAIN BOLT: A PLACE AMONG SPORTING ICONS
Usain Bolt, widely regarded as the greatest sprinter in history, has also demonstrated confidence in his place among sporting legends.
In a 2016 interview with TIME, Bolt was asked to select four athletes for his all-time sporting Mount Rushmore. His choices included Muhammad Ali, Michael Jordan, Pelé and himself.
Bolt explained his inclusion by pointing to his unprecedented achievements on the track.
His record speaks for itself. The Jamaican sprinting icon won eight Olympic gold medals and 11 World Championship titles. He also holds the men’s 100-metre and 200-metre world records, set at the 2009 World Championships in Berlin.
His 100-metre record stands at 9.58 seconds, while his 200-metre mark is 19.19 seconds.
Bolt’s achievements provide a compelling case for his place among the greatest athletes ever, even as the broader debate over sporting greatness remains subjective.
WHO REALLY DECIDES GREATNESS?
Ronaldo’s declaration raises a question that extends beyond his rivalry with Messi: does greatness depend on achievements alone, or does the way athletes present themselves also shape their legacy?
Ronaldo’s extraordinary goalscoring record, longevity and success across different leagues provide substantial arguments in his favour. Messi’s World Cup triumph, individual honours and influence on the game offer an equally powerful case for his supporters.
But the debate often becomes more heated when Ronaldo explicitly declares himself the best.
Muhammad Ali turned self-belief into a performance. Ibrahimovic challenged the importance of individual awards. LeBron James has openly argued for his place at the top of basketball history, while Bolt confidently included himself among sporting icons.
Each athlete has approached the question differently, but all demonstrate how confidence can become part of a champion’s identity.
The distinction between self-belief and arrogance often depends on perspective. Supporters may see Ronaldo’s declaration as evidence of an unshakeable winning mentality, while critics may believe that greatness carries greater weight when recognised by others.
Ultimately, there is no universally accepted formula for determining the greatest footballer of all time. Statistics, trophies, longevity, influence and personal preference all shape the argument.
Ronaldo is entitled to make his case. Whether the football world agrees is another matter.
Perhaps the most enduring lesson is that sporting greatness is built through achievements, but the debate over legacy rarely ends when the final whistle blows.
