"It was a difficult match, very tough," Cavani told reporters. "I think we attacked quite a lot but maybe we were a little bit messy sometimes and this gave us a lack of confidence or solidity in front of the goal.
"But eventually we managed to score and we were able to get three very important points for us. As the minutes tick by and we still weren't able to score, I thought it was necessary for me to drop back a bit to help win the ball.
"This is something important that we showed today and eventually it served us well for the victory."
PSG currently sit fourth in the French top division.
