Benitez admits the game will be decisive to their hopes of emerging from the group.
"Marseille are a strong team with some dangerous players so we'll have to be at our best.
"I won twice here with Liverpool and remember a spectacular goal from Torres. It's the sort of stadium that brings the best out in players.
"We have a strong team with a lot of character. I am convinced that tomorrow we will show that on the pitch.
"It will be important for both teams to win, and we will make sure the result goes our way. Marseille have lost three games in a row so it will be even more difficult for us.
"They will want to show they can win the game, but we will show our determination."
