Record-Breaking Teenagers Who Shocked the Champions League Stage

Considering the immense pressure associated with Champions League football, it's uncommon for players in the early stages of their careers to feature in this elite competition.

This is exactly why, when a young talent receives an opportunity in the Champions League, supporters worldwide pay close attention to witness what might mark the start of an extraordinary career. Whether such potential actually materializes, though, remains uncertain.

International stars such as Barcelona's Lamine Yamal, Manchester City's Rayan Cherki and Aston Villa's Youri Tielemans all made their European debuts before reaching 17 years of age, though the existing record belongs to Youssoufa Moukoko, who featured for Borussia Dortmund merely 18 days following his 16th birthday.

Moukoko has maintained this record since December 2020, surpassing the 26-year milestone previously held by Céléstine Babayaro. Best known for his time with Chelsea and Newcastle United, the Nigerian defender's achievement appeared insurmountable, yet the 21st century has witnessed numerous promising youngsters making their debut before age 17.

Europe's premier tournament has never featured a 15-year-old competitor, though Arsenal midfielder Max Dowman aims to become the first.

The Gunners prodigy, who ranks second only to Ethan Nwaneri among the Premier League's youngest-ever participants, won't celebrate his 16th birthday until December 31 and will have numerous chances to surpass Moukoko's milestone before the conclusion of the 2025–26 campaign.

Below is an examination of the 10 youngest competitors to ever participate in the Champions League.
