Javier Pastore believes Sunday's clash between Paris Saint-Germain and Marseille is a key match for both clubs.
The 23-year-old says PSG must win the match but the Argentine playmaker expects Marseille – who are three points ahead of Carlo Ancelotti's side and on top of the table – to provide a huge test.
"This is a game that will count," he told France Football.
"We must try to win to go in front (of Marseille in Ligue 1). But it will be difficult, as it was last year.
"Anyway, this year we are confident. Yes, we could lose, of course, like last season. I feel that we will be successful in a big match."
PSG sit in second place with 15 points from seven matches.
