"We did not have a great game, it's true," said Ancelotti after the match. "We should have exercised better control and should have tried to score again after taking the lead.
"This is not a bad result. We even could have won. We took the lead but we were not able to control the game then.
"It's a shame because we could have won. We gave a good performance with a good grasp of the game and a good state of mind."
The result means that PSG remain three points behind leaders Marseille in second place in the league table with 16 points from eight games.
