The German suggested he was compelled to leave Real Madrid for Arsenal due to the club's lack of faith in him, but the Italian has dismissed such claims
The Germany star joined Arsenal on transfer deadline day after Gareth Bale joined los Blancos from Tottenham, and claimed the Liga giants had shown "a lack of confidence and trust" in his abilities which prompted his exit from the club.
Ancelotti, however, insists this was never the case, claiming that the 24-year-old has simply become concerned by the increased competition for places following the summer signings of Bale and Isco.
"I heard many talk about what Ozil has said, and I want to tell my side," the Italian told reporters.
"He says we had little confidence, but Ozil played two of the first three games of the season.
"No player is leaving if they do not want to. With new competition for his starting spot, he thought he had a lot to do and asked to leave."
Ancelotti went on to stress he had no problems with the player for leaving the club, pointing to Madrid's strength in depth as proof that the player will not be missed.
"Considering we have many players in his position, from a tactical standpoint, we had no problem with him leaving," he said.
"The club received a good deal for the player, and everyone is happy now."
Ozil could make his Arsenal debut against Sunderland on Saturday.
