PSG coach Thomas Tuchel has again insisted defeat to Manchester United last week was an "accident".
PSG are still reeling after their shock Champions League elimination.
And Tuchel says: "For me, it's an accident, there is no explanation.
"We controlled the match. It's not necessary to play the best game, but you had to control it. But we made two incredible individual mistakes. And in the end there was a big mistake from the referee to use the VAR.
"Now it is very important not to do analysis too soon. It is possible that it is an accident, although I know that many will say that there are many accidents."
