"It was very complicated," Ancelotti told reporters. "Before the match I knew it would be difficult, and it was, especially in the first half. Afterwards we reacted well and played with more aggression, more intensity and more efficiency.
"The first half was like our performances at Sochaux and Reims. But at half time I told the players to show a different attitude. There was no movement, no intensity to our passing. But that's normal, it's nothing new.
"Two and a half days after a Champions League match you can't have the same intensity. The next three weeks will be important. We will be able to work well and recuperate. "
PSG are currently four points clear at the top of Ligue 1.
