After watching his brother Kylian Mbappé score for Paris Saint-Germain, 16-year-old midfielder Ethan Mbappé made his league debut for the French champion on Wednesday.

The French league leader finished the game with the two brothers on the field after the teenaged Mbappé came on for Manuel Ugarte during stoppage time in a 3-1 home win against Metz.

Kylian Mbappé scored twice on his 25th birthday to extend his league-leading tally to 18 goals.

Ethan Mbappé is as a technically gifted left-footed midfielder and came on to the field with their proud parents in the stands at Parc des Princes. He had been an unused substitute earlier this season against Nice.

He played for the same youth team as his brother Kylian — AS Bondy — and turns 17 on Dec. 29.
