Paris Saint-Germain coach Laurent Blanc was relieved to see his side progress into the Coupe de la Ligue quarter-finals after a narrow 1-0 win over Saint-Etienne.
Second-half substitute Edinson Cavani scored the only goal of the game on 86 minutes 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. "We play every three days. Physical and psychological fatigue exists.
"It is a crazy schedule. My players are not machines. It was a typical cup match.
"We never gave up, and I still had a few weapons on the bench, which allowed us to win the game.
