Uruguay international Edinson Cavani saved PSG with a late goal to seal the club's Coupe de la Ligue progression.
Paris Saint-Germain coach Laurent Blanc was relieved to see his side progress into the Coupe de la Ligue quarterfinals after a narrow 1-0 win over Saint-Etienne.
Second-half substitute Edinson Cavani scored the only goal of the game in the 86th minute to seal PSG's progression into the next round.
Blanc praised his tired side's performance despite the fatigue of playing eight games in just over three weeks.
"This is our eighth game in 23 or 24 days," Blanc said.
