The England star, 37, had his first training session on Wednesday.
And PSG boss Ancelotti revealed Becks has settled in quickly.
The Italian said: “Nothing’s changed because David’s arrived. He works hard with his team-mates and he’s very humble.
“There are no problems with the other players. There are no egos here, David has a very good relationship with the others.”
Ancelotti has confirmed tonight’s game at Sochaux has come too soon for Beckham. But the midfielder should be fit to make his debut against Joey Barton’s Marseille next Sunday.
Former Chelsea boss Ancelotti said: “David still needs to work — and with a week’s work he will be ready the following week against Marseille.
“He brings his experience, his quality, his professionalism. These are the things we need from David.
“I think he can play easily against Marseille after a week more training, no problem — not to start the match but to play.”
Ancelotti insists Becks will have a big part to play on the field over the next three months.
He added: “I’m not just keeping him for the cups or the Champions League. He can play in every match.”
