Lewandowski was said to have been left frustrated by a lack of support from his teammates to finish the 2016-17 campaign as the Bundesliga's top scorer.
Ancelotti is confident that the former Borussia Dortmund ace is happy at Bayern, however, accusing his representatives of simply 'talking too much' in the media during the off-season.
"Lewandowski has never complained to me, I finally congratulated him on his good season," he told reporters. "I was satisfied with him and he was pleased with us.
"As always there are agents who talk too much - I do not know why. It is not the first time an agent has used the newspapers to say something wrong, that's all. In a perfect world, agents do not talk."
Bayern released a statement a fortnight ago warning clubs not to bid for Lewandowski, who has netted 136 goals for club and country in the past three years.
