The former Juventus skipper says his former coach's efforts to speak the language as soon as he arrived in the French capital show his quality as a man
The Parisian side have won all five matches under the former AC Milan trainer's tenure, and Cannavaro feels the 52-year-old's capture represents a big coup for the Ligue 1 leaders.
"This is a great achievement, a great arrival for PSG," Cannavaro told RMC.
"Carlo Ancelotti is a coach who is well-known internationally, and has a record that speaks for itself.
"He's also a great man, which he has shown by making the effort to try and speak French as soon as he arrived."
Paris Saint-Germain hold a three-point lead over Montpellier at the top of the Ligue 1 table after 22 rounds. They will continue their bid for a first league title since 1994 with a trip to Nice on Sunday afternoon.
