"That was without a doubt our best match in 2013," Ligue1.com quotes Ancelotti as saying.
"We rediscovered the kind of form in attack that we had before the winter break. It was a very good performance.
"We didn't play so well against Ajaccio and Lille, but you can't be 100% all the time. What's important for the club is that we keep racking up positive results."
PSG host Bastia at the Parc des Princes on Friday.
