The PSG coach is still looking for his first win of the season after a second successive draw, but insists the side from the capital are improving
PSG struggled to create opportunities and their task was made even harder when Ezequiel Lavezzi was dismissed in the 59th minute.
"The exclusion of Lavezzi was fair, I was a little upset. There was a lot of aggression towards Ajaccio. In addition, we played the first half with a bit of complacency," Ancelotti told France Football.
"This is a disappointment because we have the quality, the skill. But there is a good balance on the pitch."
A Zlatan Ibrahimovic double saved Ancelotti's blushes last weekend, but none of his big money signings could conjure up a late goal this time around, with the Italian pointing to a lack of match fitness.
"We have no goals, but we have not had many opportunities, except for [Jeremy] Menez. Last time [against Lorient], we had 10 or 12 opportunities, this time only one.
"Physically, maybe some are not 100 per cent. I do not think that PSG [are] too far away from what [we] can do. With Ibrahimovic and Thiago Motta, it will improve the quality of the team.
"We must work to find a better balance and a better organisation because there are a lot of new players."
Les Parisiens will continue their hunt for their first victory of the new season when they welcome Bordeaux to the Parc des Princes next weekend.
