Sunday's tame 1-0 defeat against Rennes, sealed by a 76th-minute header by Jimmy Briand, means PSG have been beaten four times in a row in the league.

They remain second from bottom, although the results of their relegation rivals at the weekend sees them just two points adrift of safety.

Owing to the international break, PSG have a 15-day gap until their next match, an away game at Lens - where the capital club have not won in 10 years.

This latest defeat comes four days after they were dumped out of the UEFA Cup by Benfica, thanks to a last-minute Simao Sabrosa penalty.

"In these last few days, we are going from disappointment to disappointment," said Le Guen.

"We have committed errors which have exposed us. In the last few matches, you could say we haven't had the rub of the green, but we mustn't hide behind that.

"We must accept our situation. What we have been doing is far from being bad. To stay up, it will be very hard, but everything is to play for.

"We are playing for our future each match."

Striker Bonaventure Kalou added: "We are in a difficult spiral. But we mustn't get down about it all.

"During the break, we are going to think of other things. Nothing is over yet.

"We must look at adversity in the face and say to ourselves that there is still life, still hope."

PSG, who have won just two of their last 18 games, were thankful Sedan could only draw 1-1 with Bordeaux on Saturday, otherwise they would be bottom of the table.

Another team having a few problems at the moment, Lens, also lost 1-0 on Sunday, to Auxerre.

Thomas Kahlenberg scored the only goal of the game in the 17th minute as Auxerre moved into mid-table.

Second-placed Le Sang et Or, meanwhile, slipped to their second defeat in five days, although they do stay five points ahead of the chasing pack in the race for an automatic Champions League berth for next season.

The fact that the teams behind them - Bordeaux, Lille and Toulouse - all failed to win at the weekend made this defeat all the more galling for Lens coach Francis Gillot.

"We would have been able to make a break from our direct rivals with a win here," he said.

"I hope we don't regret that in a month or two."
