Kylian Mbappe's 15-year-old brother Ethan made his first senior appearance for Paris Saint-Germain in a friendly against Paris FC on Friday.
Ethan Mbappe replaced midfielder Fabian Ruiz as Christophe Galtier rang the changes at half-time, after Nordi Mukiele had given PSG a 1-0 lead at the Camp des Loges training centre.
The Ligue 1 champions went on to claim a 2-1 victory, with the teenager featuring alongside senior players including Sergio Ramos, Marco Verratti and Renato Sanches.
Ethan Mbappe joined PSG from AS Bondy in 2017 before signing a new three-year contract with the club in June 2021.
The midfielder, who was called up to France's under-16 squad last year, took to Instagram after the game, writing: "Very excited for my debut in the pros."
With Kylian Mbappe looking to cap another fine World Cup campaign by leading France to a second successive triumph at the tournament on Sunday, it could be a particularly memorable week in the Mbappe household.
