From keeping out goals to scoring them, over the decades some of the Champions League’s biggest names have announced their arrival with eye-catching feats before their 20th birthday
Imagine you’re 16 years old and sitting in a classroom. No doubt bored out of your mind. Then in comes the headmaster, a hint of panic and excitement in his voice as he tells you to drop everything and take a taxi to the airport – Real Madrid need you for a Champions League game in Norway. For many teenagers, it’s the stuff of daydream fantasy. For Iker Casillas, it was his introduction to the big time.
“It felt like winning the lottery,” he later recalled. “I left school, went home, changed my clothes, got in a taxi to Barajas and I met all the stars – everything you thought impossible when you were a kid.”
The young goalkeeper remained on the bench as Madrid lost 2-0 away to Rosenborg, but he did not have to wait long for his chance, emerging as first choice at the age of 18 during the 1999/2000 campaign. “His maturity is peculiar,” said Manchester United boss Sir Alex Ferguson after one of Casillas’ 12 Champions League outings that season, which ended with Madrid beating Valencia 3-0 in the final, just four days after their fresh-faced custodian had turned 19.
If Casillas remains the youngest keeper to win the Champions League, the record for youngest final goalscorer is also getting on in years. Patrick Kluivert began the 1995 showpiece on the bench for Ajax, but his mother Lidwina had promised coach Louis van Gaal that her son would nab the winner against AC Milan – and so he did, Kluivert poking in the only goal of the game with five minutes remaining.
Remarkably, the powerful forward was one of three teenagers in that youthful Ajax side. Future midfield great Clarence Seedorf started the Vienna final aged 19, later being replaced by Nwankwo Kanu, still the youngest player to lift the trophy in the Champions League era (18 years, 296 days).
A gamble? Far from it. “Milan were more experienced than us,” explained Van Gaal. “That’s why I put two 18-year-old boys on the field in the second half, and they won it for us.” Indeed, the Dutch giants have retained their faith in youth ever since, notably making Matthijs de Ligt the youngest-ever Champions League captain at the age of 19 in 2019.
While scoring the winner in a final is hard to beat for a teenage tyro, notching a hat-trick on your Champions League debut is nothing to sniff at either. Erling Haaland has been chopping up the record books in recent years, proving it was no fluke when he terrorised Genk as a 19-year-old in 2019, hitting three goals in his first Champions League appearance with Salzburg. As team-mate Maximilian Wöber correctly predicted, “He’s going to become one of the best strikers in the world.”
The hype will have felt familiar to Wayne Rooney, who was even younger at 18 when he marked his own Champions League bow for Manchester United with a hat-trick against Fenerbahçe in 2004. But while the English press went into a frenzy, Sir Alex struck a note of caution, urging fans “to allow the boy to develop naturally without too much public attention”.
It was shrewd advice, given the long list of teen prospects who have seized the limelight only to fall away. Early exposure can be a curse as much as a blessing – though, in Rooney’s case, Rio Ferdinand wasn’t too concerned. “I don’t think he knows what pressure is,” remarked the United defender, hinting at the fearlessness that can fuel outrageous feats from young stars.
Examples abound, from a twinkle-toed prodigy named Lionel Messi opening his account against Panathinaikos at the age of 18 to Jude Bellingham commanding the midfield for Dortmund at 17. After all, while every coach must judge how their player will cope with the occasion, sometimes a talent is too overwhelming to keep wrapped in cotton wool.
Supreme ability and youthful exuberance are a potent combination – and perhaps no teenager better demonstrated that on a regular basis than Kylian Mbappé. The French phenomenon plundered a record 13 Champions League goals before his 20th birthday, kicking off with home-and-away efforts for Monaco against Manchester City in 2016/17. “I must confess I don’t know him,” City midfielder Kevin De Bruyne had admitted before that round of 16 tie. Like the rest of us, he knows now.
