This year's season-ending scenario has a strong sense of deja vu for both clubs but the boot is on Blanc's other foot.
A draw would be enough for Blanc's Bordeaux, who lead by three points from Marseille, when they play at Caen. They will also be crowned champions in defeat if Marseille fail to win at home to Stade Rennes.
"The title race will be decided on the last day and it is not an ideal situation," Blanc told reporters after Bordeaux extended their winning streak in the league to 10 games last weekend.
"My players know very well what is at stake and they are a bit nervous but I guess it is the same at Marseille," he added.
"Caen simply must win if they want to escape relegation and that is a point in our favour," Marseille coach Eric Gerets was quoted as saying on his club's website.
"If we had a normal record at home, we would already be champions," Gerets said.
"I hope my players will have learned the lesson of all those previous games at home because we can experience a beautiful end to our season and, with luck, have a great party," the Belgian added before his last game on the Marseille bench.
