Paris Saint-Germain manager Carlo Ancelotti has said that his side must get back to winning ways against Ajaccio.
Les Parisiens have recorded three consecutive draws in Ligue 1, leaving them two points behind Montpellier HSC at the top.
The Italian believes that the game against Ajaccio is one they must win if PSG want to be champions.
"Ajaccio aren't high up the ladder, but have got some good results in their last eight games," said the 62-year-old. "
"They're playing very well at the moment and I think it's going to be a very tough match. We want to get back to winning ways after three consecutive draws.
"If we want to be champions, it's very important to win on Sunday and play well because Ajaccio are a form side."
Ancelotti took over at the Parc des Princes in December.
