The Paris Saint-Germain head coach played down some of the Swedish front man's inflammatory remarks towards the fans and stressed that he is ready to face Saint-Etienne.
The Swede was highly critical of the boos and whistles that came from the home support when Les Parisiens fell behind during last week’s 2-1 win over Nancy. He stated that he found the ungracious reaction from fans strange considering "they had nothing before," referring to the previous era of PSG before the high-spending reign that saw the club sign Ibrahimovic, among a number of other stars.
Ancelotti dismissed any idea that this showed the striker could be looking to leave the club in the wake of the controversy his comments created, though.
"Ibrahimovic said something after the match against Nancy," Ancelotti told RMC Sport. "It is true that we have not had a good game, but we were surprised.
"This is an important time of the season and it is important that the fans are behind us. Ibrahimovic explained this very well after the game."
Les Rouge-et-Bleu could extend their lead over Olympique Lyonnais to seven points with victory on Sunday, and Ancelotti was quick to support the former Barcelona and Inter forward.
"There is no problem [with Ibrahimovic]," Ancelotti said. "He is very motivated and focused on Sunday's game. He is serious and wants to win, as do the whole team."
PSG currently sits atop of Ligue 1 with 57 points from 28 games.
