The manager believes his side have the advantage over his side's rivals, while revealing that Jeremy Menez has been dropped for his reaction on Wednesday
The tie is the biggest rivalry in French football and has the added spice of both sides being in the Ligue 1 title race along with the likes of newly promoted multi-millionaires Monaco and defensively impressive Lille.
Blanc has insisted that PSG's home clash with Marseille could have a large bearing on the title race and believes Sunday's Classique will be a "special game".
"This is a game of a very high standard, with big clubs," the 47-year-old told reporters on Saturday. "The dynamics are favourable to us, but Marseille is only one point behind us. So in the championship, they also have good momentum.
"All games are up for grabs and worth three points. If they [Marseille] are direct competitors, it may be interesting, but we do not know that today because the championship is long. Points need to be taken against all teams.
"After that, it is a special game, as we know. Between Paris and Marseille there is no love, they are cities with different mentalities."
Menez has been punished for storming out the dugout in PSG's 3-0 Champions League win over Benfica on Wednesday after not being brought off the bench with 20 minutes left, with Blanc leaving him out the squad for their clash with Marseille.
"Jeremy has met with the club officials, I have met with him this morning [Saturday]" the ex-France boss added. "There will be a sanction. He will not be with us for the Marseille trip."
