Les Parisiens ran out narrow winners thanks to an own goal from Aurelien Chedjou, meaning the goalkeeper has now not been breached in his last seven Ligue 1 outings.
But the Italian preferred to focus on his side coming through another stern test and admitted the visitors had made life hard work for the Ligue 1 leaders.
"I was told about this record, but I did not want to be put under pressure, especially for such a delicate game," he told reporters after the game.
"But I'm pleased. It was a difficult match in its entirety. This is football and it's not a problem for us. We suffered a lot but we scored a lucky goal. We saw out the result and we are very happy for this."
Carlo Ancelotti's side travel to Toulouse next Friday and could put breathing space between themselves and second-placed Olympique Lyonnais, with the pair level on 45 points and les Gones playing 48 hours after their title rivals.
