The Parisiens saw their lead at the top of the table cut to three points as they went down 3-2 at the Stade Auguste Bonal.
"Sochaux are a good compact team," Ancelotti told reporters. "I've seen many games of Sochaux so I am not surprised by their performance."
PSG continue their league campaign on Sunday when they entertain third-placed Marseille.
