Thomas Tuchel said he could not defend his Paris Saint-Germain players after they were stunned 3-2 by Nantes on Wednesday.
The defeat followed a 5-1 thrashing by Lille in their previous match, but Tuchel felt their performance against Nantes was worse.
Per Goal's Dejan Kalinic, he said:
"In Lille, we controlled the game during 60 minutes, many players were injured. It was a game with a Champions League level. It was different.
"Today, we didn't perform in 90 minutes. There was no performance, no performance at all. So it was impossible to win.
