Quentin Ndjantou Mbitcha was born on 23 July 2007 in Arpajon, Essonne, France. He came through RC Arpajonnais, Paris FC, and US Villejuif before joining Paris Saint-Germain's youth ranks in 2020. With PSG's U19 he has won consecutive Championnat National U19 titles in 2024 and 2025.
On 28 July 2025 Ndjantou signed his first professional contract with PSG, running through June 2028. He made his professional debut for PSG on 27 September 2025 in a 2–0 Ligue 1 win over Auxerre, and across 2025–26 he logged 15 senior matchday minutes — including a starting role in a UEFA Champions League fixture against Tottenham, an early-career milestone for a teenage academy graduate. He scored his first professional goal during the season, assisted by fellow academy graduate Ibrahim Mbaye.
A forward who can play as a left winger or attacking midfielder, Ndjantou combines pace, technical refinement, and the dribbling instincts that have come to define PSG's modern academy attacking pipeline. Unfortunately his 2025–26 season was disrupted by a hamstring injury requiring surgery and a multi-month recovery, slowing his momentum just as he was being integrated into the senior matchday rotation.
He represents one of the most advanced of the wave of 2007-born academy talents PSG have invested in, and projects as a long-term first-team contributor.
