#3 Didier Domi — 16 years, 8 months, 22 days
Didier Domi is a forgotten name among the ranks of PSG. He was with the Parisian giants before they attained elite status in European football.
Domi joined Paris Saint-Germain as a youth recruit and earned a professional contract at the club before he turned 17. His debut came in the Coupe de la Ligue Round of 16 clash against Lyon in 1996 when he was aged 16 years, eight months, and 22 days.
Domi remained with PSG for another two years before joining Newcastle United in 1999. However, his performances for the English side once again attracted the attention of his boyhood club. The Parisians subsequently approached the Magpies to buy the defender back.
Unfortunately, the Frenchman's return to Paris Saint-Germain was marred by injuries, and he fell down the pecking order at the club. He was eventually offloaded to Leeds United as a loanee before joining Espanyol in 2004.
The former defender made 113 appearances for PSG across all competitions, scoring one goal and providing one assist. He currently works for beIN Sports in the Middle East.
#2 Kingsley Coman — 16 years, 8 months, 4 days
Kingsley Coman began his career with French side US Senart-Moissy in 2002, when he was six years old. He joined Paris Saint-Germain's youth academy in 2004 at the age of eight. He spent nine years in the youth set-up and eventually earned a promotion to the club's senior team.
After spending nine years in PSG's youth system, Coman made his professional debut for the club in February 2013 when his side suffered a 3-2 league defeat to Sochaux.
Coman spent only two seasons with the French giants. He made just four appearances for the senior side across all competitions in that period.
The winger currently plies his trade for Bundesliga heavyweights Bayern Munich.
#1 El Chadaille Bitshiabu — 16 years, 7 months, 3 days
El Chadaille Bitshiabu joined Paris Saint-Germain's youth set-up from Athletic Club Boulogne Billancourt in 2017 at the age of 12. His performances during his academy days earned him an aspiring contract in 2020, at the age of just 15.
The teenager signed his first professional contract with PSG in July 2021. He made his debut for the club in a 3–0 win over Feignies Aulnoye in the Coupe de France in December 2021. At the time, he was aged 16 years, seven months, and three days. In the process, he broke Kingsley Coman's record to become the youngest ever player to debut for the French side.
The center-back has made two appearances for PSG's senior side so far.
