The France international says it is important they make home advantage count in their Champions League quarter-final against the Blaugrana
The midfielder is proud of their achievement in making it this far in the competition but admits they are underdogs against the Catalan giants.
"It is important to get a good result at home because over there, it will be complicated," the 25-year-old told L'Equipe.
"What we have done, it is already beautiful, but we want to go even further.
"Let's not lie, we are outsiders. If we can beat them, it will be a feat. But we will do everything to try to thwart them."
Les Parisiens face the Blaugrana at the Parc des Princes on April 2 before travelling to Spain on April 10 and the former Saint-Etienne man says the draw set up a glamour tie.
He added: "It will be a magical game, that's for sure.
"It will be a beautiful spectacle with the entire nation behind us which hopefully will help the team perform on the pitch."
