Lionel Messi: Career, Disease, World Cup & GOAT Debate

Few football careers begin with a medical diagnosis that nearly ends them before they start. Lionel Messi’s journey from a boy with growth hormone deficiency in Rosario to an 8-time Ballon d’Or winner is a story of resilience, sacrifice, and an improbable move at age 13.

Ballon d’Or wins: 8 · FIFA World Cup titles: 1 (2022) · Goals for FC Barcelona: 672 · Inter Miami goals (through 2024): 34 · Assists for Argentina national team: 58 · Ligue 1 titles with PSG: 2

Messi’s formal profile reveals a player built from adversity.

What is Messi’s disease called?

Growth hormone deficiency diagnosis

Messi was diagnosed with growth hormone deficiency (GHD) at age 11 in Rosario, Argentina, in 1999 (Dartmouth Journals – medical analysis). GHD is a rare condition caused by inadequate secretion of growth hormone from the pituitary gland, affecting approximately 1 in 3,000 to 1 in 10,000 children (Dartmouth Journals – prevalence data). Without intervention, doctors predicted Messi would reach a maximum height of about 4 feet 7 inches (Dartmouth Journals – height prognosis).

Treatment and impact on his career

His treatment involved nightly self-administered injections of synthetic human growth hormone (Michigan Tech Law Review – treatment method). The family struggled to afford the therapy until FC Barcelona agreed to cover the cost after Messi’s trial at age 13 (Michigan Tech Law Review – financial coverage). This medical intervention allowed him to eventually reach 5 feet 7 inches (170 cm) and pursue elite football (Dartmouth Journals – treatment outcome).

What happened to Messi at age 13?

In 2000, at age 13, Messi moved from Rosario to Barcelona with his father after the club offered to fund his growth hormone treatment and enroll him in La Masia academy (The Athletic / Tifo Football – biography overview). The agreement was finalized after an informal understanding that the club would cover medical expenses, a decision that shaped the rest of his career.

Bottom line: Messi’s growth hormone deficiency was a career-threatening condition that only elite medical care and Barcelona’s financial support turned into a manageable chapter. For young athletes diagnosed with GHD, early intervention and institutional backing are decisive factors.

Who is best, Ronaldo or Messi?

Five key measures separate the two legends: individual awards, World Cup titles, goal totals, playing style, and longevity.

Head-to-head statistics and trophies

Messi leads in team trophies with 46 to Ronaldo’s 34, but the gap is narrower when considering league titles and Champions Leagues. Both have dominated European football for two decades, but Messi’s 2022 World Cup win is often cited as the tiebreaker in the GOAT debate (FIFA – World Cup profile). The pattern: Messi’s international breakthrough gave him a trophy Ronaldo hasn’t achieved, yet Ronaldo’s goal tally remains slightly higher.

Net worth comparison: Messi vs Ronaldo

While exact net worth figures vary, Forbes has estimated Messi’s net worth at around $600 million and Ronaldo’s at $500 million (2024 estimates – Forbes – wealth rankings). Endorsement deals with brands like Adidas (Messi) and Nike (Ronaldo) supplement their on-field earnings. The catch: both players generate more income off the pitch than on it, making net worth a constantly moving target.

Who is the GOAT in football?

Fans and pundits remain divided, but the numbers favour Messi in individual awards and World Cup success, while Ronaldo leads in Champions League titles (5 vs 4) and international goals. The editorial verdict: Messi’s 2022 World Cup victory and 8 Ballon d’Or awards give him a statistical edge, but the debate is as much about personal preference as objective data.

Bottom line: Messi vs Ronaldo is football’s most enduring rivalry. For fans valuing World Cup glory and creative flair, Messi wins. For those emphasising goal-scoring consistency and physical dominance, Ronaldo remains competitive. Neither case is conclusive.

Will Messi play the 2026 World Cup?

Messi’s statements on future

Messi has repeatedly said he will continue playing “as long as I feel good” and that retirement is not imminent (Fox Sports – 2024 interview). He turns 39 during the 2026 tournament (June 24, 2026), making him one of the oldest outfield players in World Cup history if he participates.

Retirement plans after 2026?

Argentina coach Lionel Scaloni has stated that while Messi is fit, he will be selected for the 2026 World Cup squad (FIFA – coaching statements). Messi has not explicitly ruled out retirement after 2026, but he has hinted that his family and physical condition will guide the decision.

Will Ronaldo be in the 2026 World Cup?

Ronaldo turns 41 in February 2026. However, Portugal has not yet qualified for the 2026 tournament; European qualifying will determine their participation (FIFA – 2026 qualified teams). As of early 2025, Argentina is confirmed among qualified teams, giving Messi a clearer path to a sixth World Cup appearance.

The implication: Messi’s path to the 2026 World Cup is more certain than Ronaldo’s, due to Argentina’s automatic qualification. This could set up a scenario where one iconic player participates while the other does not – a stark contrast in their careers.

Bottom line: Messi’s fitness and desire will decide his 2026 World Cup participation. For Argentina fans, his presence would extend a legacy built on overcoming early obstacles; for Portugal, Ronaldo’s absence would highlight the unforgiving nature of qualification.

Who was better at 17 Yamal or Messi?

Statistical comparison at age 17

Lamine Yamal (born 2007) made his Barcelona first-team debut at age 16 and quickly accumulated over 50 senior appearances, whereas Messi had just one first-team appearance for Barcelona at 17 (Wikipedia – Yamal career). Messi scored his first senior goal at 17 (May 2005), while Yamal scored his first La Liga goal at 16 (October 2023).

Lamine Yamal’s early career vs Messi’s

Yamal’s minutes and assists at 17 exceed Messi’s, but era and team context differ. Modern football gives young talents earlier exposure due to revised training methods and tactical structures. Nonetheless, Yamal’s 2024 European Championship performance at 16/17 has drawn comparisons to Messi’s early breakthroughs (FIFA – youth development trends).

Context of modern football development

The pattern: Yamal benefits from a more data-driven, earlier-integration approach in Barcelona’s academy, while Messi’s path was delayed by his medical condition and relocation. Neither path is objectively “better” – they reflect different eras in football development.

Bottom line: Yamal’s statistical output at 17 is higher, but Messi’s career trajectory from 18 onwards is unprecedented. For scouts, Yamal shows advanced maturity, but Messi’s late bloom was driven by unique medical and tactical factors.

Which footballer grew up in poverty?

Messi’s childhood in Rosario

Messi’s family struggled financially in Rosario, Argentina. His father worked as a steel factory manager and his mother as a cleaner. The cost of growth hormone treatment pushed the family to relocate to Barcelona after the club agreed to pay (Dartmouth Journals – family financial strain). Messi has often credited his humble beginnings as motivation.

Ronaldo’s upbringing in Madeira

Cristiano Ronaldo grew up in a poor family in Funchal, Madeira, sharing a small room with his siblings (FIFA – Ronaldo biography). His father worked as a gardener, and his mother as a cook. Both players used football as a way out of poverty, but their paths diverged: Messi’s medical needs required institutional support, while Ronaldo’s development followed a conventional elite academy route.

How poverty shaped their careers

The trade-off: poverty forged relentless work ethic in both players, but it also meant Messi nearly lost his career to an untreated condition. Ronaldo’s relatively stable growth allowed him to focus solely on technical development. The catch: without Barcelona’s financial intervention, Messi’s story might never have happened.

Bottom line: Both Messi and Ronaldo came from poverty, but Messi’s case is more medically precarious. For aspiring players from low-income backgrounds, the lesson is that institutional support can be as critical as talent.

Why are there so many over-40 players at the 2026 World Cup?

Medical and training advances

Improved sports science, nutrition, and recovery methods allow professional footballers to maintain elite performance into their late 30s and beyond. FIFA’s lack of an age limit means players like Messi (39) and Ronaldo (41) can compete provided they qualify (FIFA – no age restriction).

Examples of over-40 players in football history

Goalkeepers have often played past 40 (e.g., Gianluigi Buffon retired at 45). Outfield examples are rarer but include Japan’s Miura (50), Ibrahimović (41), and potentially Messi and Ronaldo in 2026. The trend reflects advances in recovery and injury prevention.

Messi and Ronaldo as part of this trend

Both players are expected to extend their careers beyond 40, but Messi’s less physically demanding style (fewer sprints, more playmaking) may aid longevity. Ronaldo’s power-based game relies more on athleticism, which typically declines faster. The editorial conclusion: the over-40 trend is driven by data-driven training, but each player’s longevity depends on position and playing style.

Bottom line: The 2026 World Cup could feature more over-40 players than ever, with Messi and Ronaldo as poster boys. For fans, it’s a chance to see legends in their final tournament; for younger players, it raises the bar for career management.

For Argentina and Inter Miami fans, the possibility of Messi’s 2026 World Cup appearance is not just a milestone – it exemplifies how modern medicine and institutional support can salvage a career from a childhood diagnosis. For rival supporters, the implication is clear: Messi’s legacy will only grow if he adds a second World Cup at 39, setting a new benchmark for longevity in elite football.

Messi’s friendship with Luis Suarez is a notable aspect of his Barcelona years, and the Women’s Champions League Final 2026 highlights the global football landscape he helped shape.
