Kylian Mbappe featured for AS Monaco in their friendly against Stoke City on Saturday.
The 18-year-old forward is one of the hottest prospects in European football and has attracted the attention of Arsenal and Real Madrid.
However, he put the speculation over his future behind him as he took to the pitch in Monaco's 4-2 victory over the Potters.
Saido Berahino put Stoke ahead before Manchester United target Fabinho levelled from the penalty spot.
Mame Biram Diouf cancelled out Saint-Maximin's effort before late goals from Radamel Falcao and Kevin N'Doram earned Monaco victory.
