The 16-year-old, younger brother of Kim Tillie, who plays his basketball in Spain's top division, dominated the competition averaging 13.6 points-per-game as well as 9.6 rebounds.
He saved his best performances for the big moments too as he was central to his team's 78-65 defeat of Turkey in the semi-final before going for 25 points and 18 boards as they swept aside Latvia 78-53 in the final.
This nomination provides justification, if it were needed, that the youngster made the right decision in giving up a promising career in volleyball to become an integral part of France's youth basketball programme.
It also caps a fine summer for French youth basketball, which has now won the first and last youth events of the summer following their victory in the U20 European Championship Women in Udine last month.
Tillie was selected as the competition's outstanding player by the panel of head coaches.
The panel also selected the four players to line-up alongside the MVP in the tournament's top five.
