The Germany international, expected to play against England on Tuesday, recently claimed his departure was down to the fact Ancelotti did not believe in him.
Ancelotti is quoted by the Daily Star: "Ozil wasn't comfortable. I knew he'd been speaking with another club because he wanted to leave.
"Mesut understood that he had competition, that he wouldn't be able to play every game - and 'I'm off' was his answer.
"I prefer to have Angel Di Maria for the team's balance. Di Maria is better than Ozil for group dynamics."
