The Italian trainer has overseen the club's third consecutive draw of the season, but insisted that it will take time for his new signings to gel
Les Parisiens were booed off at the full-time whistle, slipping to 11th place in the standings, after three draws from their opening three games of the season.
Despite Zlatan Ibrahimovic's return, the side remained profligate, with the likes of Nene, Javier Pastore and others failing to trouble a resolute Bordeaux back-line.
"We did not play good football. We played without speed and away from opposing goal." admitted Ancelotti to reporters after the game.
"We must not lose confidence, we will improve. The team was more aggressive and well organized. But we must win by playing more quickly to the attacking midfielders.
"New players have arrived or returned from injury. We must work more naturally like we did last year."
