The Italian coach has revealed that he will be resting a number of players who played against Olympique de Marseille for his next match against Stade de Reims
The 37-year-old midfielder made his debut for les Parisiens in a 2-0 victory over Olympique de Marseille at Parc des Princes on Wednesday.
PSG are top of Ligue 1 - four points ahead of Olympique Lyonnais and eight ahead of Marseille - but, with Champions League aspirations to consider, the Italian wants to shuffle his squad.
"Beckham will not start," the 53-year-old told reporters in the pre-match press conference.
"The players who didn't play on Wednesday will play. Thiago Motta won't play on Saturday, Maxwell will rest, Jallet suffers from an injury and will not play.
"I’ll decide after training. We have lots of players fit, I do not have many problems. I will make changes again but I won't take risks."
The team from the capital of Champagne lie 17th in Ligue 1 but the former Chelsea and AC Milan coach warns against complacency, especially with Lyon lurking so close to them in the French top tier.
"The objective will not be easy," he added. "Reims are good right now. I don’t think Paris has an advantage by playing before Lyon, as they are pushing us from below.
"We will have to do our best and be ready for all upcoming games."
Ancelotti also remarked on Joey Barton's comments on Zlatan Ibrahimovic following PSG's clash against Marseille, after the midfielder spoke about the Sweden striker's "big nose".
"The whistles were good for Ibrahimovic, he was very motivated for the cup. He knows he has a big nose, it's one of his characteristics," added Ancelotti.
PSG face Valencia in the second leg of their last 16 Champions League bout with Valencia, and though they hold a 2-1 advantage heading into the home clash they will be without suspended star striker Ibrahimovic.
