PSG manager Thomas Tuchel would have been a little embarrassed after fielding a reserve side, as they were held 4-4 draw by 19th placed Amiens SC.
PSG will be facing Borussia Dortmund in the first leg of their Champions League round of 16, two days later.
He rested three of his key defenders, forcing Ander Herrera to play in the right back while fielded 19-year-old Mitchel Backer on the left back position as 17-year-old centre-back Tanguy Kouassi.
Amiens took the chance by scoring three goals in the first half through Serhou Guirassy in the 5th minute, followed by Gael Kakuta in 29th minute before Fousseni Diabate scored the third goal in 40th minute.
Despite playing in an unfamiliar position, Ander Herrera managed to score a goal just before half-time.
PSG begin to turn things around as youngster Kouassi scored two goals in the 60th and 65th minute, both through a header, making it 3-3.
PSG took the lead for the first time in the game as Mauro Icardi scored a tap-in the 74th minute.
But PSG were punished by Amiens once again as Guirassy scored the equaliser just before the final whistle.
