Jallet thinks that the match could be key in the French title race, even at this early stage of the season.
The 28-year-old told reporters at a pre-match press conference that he believes the match at the Stade Velodrome will provide a good acid test of PSG's credentials.
He said: "The win over Lille proved to be a turning point for us.
"Marseille have been in stable form, as well as possessing a physical advantage, but let's hand them a slapping. This match will prove to see how well we can do in the league, and indeed if we can beat anyone."
