Paris St. Germain go into this weekend's second round of the French championship hoping they can maintain the form they showed in last weekend's opener against St. Etienne.
Last season's French Cup winners produced an impressive performance to win 3-1 although the game was overshadowed by crowd violence which looks likely to result in 250 of their notorious fans being banned from their Parc des Princes home.
"There is no particular pressure in this match but it is our first real test," says Landreau who played in Lille's opening 1-1 draw with Rennes.
"You can sense that the supporters really want to beat Paris and we are desperate to win our first game at home."
Landreau, however, is in no doubt about the task ahead of them against a PSG side that is itself desperate to land its first league title since 1994.
"Paris have rebuilt well since I left. The team has shown it wants to live up to the attacking ideals it showed in pre-season," he said.
"We have won one match, it would be madness to say that," he said. "We beat Marseille which is wonderful for those who don't really know the Velodrome or Ligue 1.
"I hope they really enjoyed but now we have other things to think about. The objective remains staying up."
The downside of the win was a broken toe for their influential midfielder Benjamin Nivet which rules him out of another tough match at home to a Lyon side that was held to a goalless draw at home to Monaco.
