Paris Saint-German announced on Friday that the younger brother of Kylian Mbappe, Ethan, had signed a youth contract with the club.
Ethan Mbappe, 15, has signed a three-year contract which will keep him with the club until 2024.
Kylian Mbappe, who is currently with France at Euro 2020, is under contract until June 2022.
However, media reports in France claim that the 22-year-old is looking to leave the club with both Liverpool and Real Madrid reported to be interested in signing him.
The signing of his brother could be a win-win for PSG as it could keep Kylian at the club and may be a discovery of another talented Mbappe.
