Senny Mayulu

Paris Saint–Germain

On 25 June 2021, Mayulu signed a new three-year youth contract with Paris Saint-Germain (PSG). On 25 October 2023, he scored the winning goal in a 1–0 UEFA Youth League win over the AC Milan under-19s, a goal that was described by Le Parisien as "superb". Less than a month later on 14 November, he was called up by senior head coach Luis Enrique for his first training session with the first team. In December 2023, L'Équipe described Mayulu as one of the "most promising" players in the Paris Saint-Germain Youth Academy.

On 7 January 2024, Mayulu made his professional debut for PSG as a substitute in a 9–0 Coupe de France win over Revel in the round of 64. Five days later, PSG announced that he would integrate the first team as part of the "elite group", joining teammates Ethan Mbappé and Warren Zaïre-Emery. In the round of 32 of the Coupe de France on 20 January, Mayulu scored his first professional goal, a lob over the goalkeeper in a 4–1 victory against Orléans.

On 18 March, he made his Ligue 1 debut as a substitute in a 6–2 win over Montpellier. On 6 April, he started his first senior match against Clermont; he went on to score a goal that was later disallowed by VAR due to a foul by his teammate in the build-up. On 24 April, Mayulu made his second start for PSG in a match against Lorient, providing his first career assist for Ousmane Dembélé's opening goal in a 4–1 victory. He signed his first professional contract on 20 May, a deal until 30 June 2027.

On 19 October 2024, Mayulu scored the opening goal of a 4–2 win over Strasbourg, his first in Ligue 1. On 19 February 2025, he scored his first UEFA Champions League goal in a 7–0 win over Brest in the knockout round play-offs. On 31 May 2025, Mayulu came off the bench to score the final goal in the 2025 UEFA Champions League final, a 5–0 victory over Inter Milan, to become at 19 years and 14 days the youngest Frenchman to score in a UEFA club competition final, and the third-youngest player, behind Patrick Kluivert and Brian Kidd, ever to score in a Champions League final. The following month, on 15 June, Mayulu scored PSG’s third goal in a 4–0 win against Atlético Madrid in the 2025 FIFA Club World Cup, to become at 19 years and 28 days the youngest French player to score in the Club World Cup, surpassing the previous record of 20 years and 297 days set by Nicolas Anelka in the 2000 edition.
