Xavi Simons, 16, trained for the first time with the PSG first team.
Various stars are off for international duty so Thomas Tuchel called up the former Barcelona youth player into the main squad to work on Thursday.
He never had the chance to do the same at Barcelona.
Despite his young age he worked with Di Maria, Kimpembe and Juan Bernat, among others. However when Neymar and Co return, Simons will go back to his level.
