Blatter described the Portuguese as being "like a commander on the pitch" and joked he spent more money on his hairstyle than Barcelona rival Lionel Messi, in an audience with Oxford University students last week, reports Xinhua.
"It seems to me like a lack of respect," Ancelotti said Tuesday.
Ronaldo aims to topple Messi to win the Balon d'Or for the first time in five years after both men were nominated in the 23-man shortlist for the award Tuesday.
Ancelotti also confirmed that Real president Florentino Perez has sent a letter to FIFA asking them to rectify Blatter's comments.
