Paris Saint-Germain coach Carlo Ancelotti has warned his side against underestimating Sochaux on Sunday.
Hosts Sochaux will head into the encounter third from bottom in Ligue 1 with 23 points from 24 matches.
"Everybody knows this is a very important game," he told reporters. "We are six points ahead and we want to keep this margin.
'We are focused on tomorrow's game. Sochaux are a good team that plays good, dynamic football. I do not think they will stick to defence – they will play to win."
PSG are currently five points clear at the top of the table.
