PSG's 10th league victory and fourth from their last five matches - in a season which has seen them come disastrously close to the relegation zone's bottom three - was however bad news for their hosts' European aspirations.

Toulouse's first home defeat of 2007 has left them in fourth place and compromised their unlikely bid to finish second and claim a spot in next season's Champions League.

The hosts however were given good reason to believe this was their night.

Toulouse took a ninth minute lead through Fode Mansare, who slalomed his way through five PSG defenders before beating Mickael Landreau in the PSG goal.

However PSG regathered their confidence to hit back with goals from Peguy Luyindula, Edouard Cisse and Jerome Rothen.

PSG may not yet be mathematically assured of top flight survival. But for their manager Paul Le Guen, who took on the job of saving their season after being ousted from Rangers, they might as well be.

"I'm very optimistic (of beating relegation), even though mathematically we're not in the clear yet," said the Frenchman, whose side moved up to 14th nine points ahead of third-from-bottom Troyes.

"But to look at the league standings, for sure we've given ourselves a huge boost."

Toulouse had what seemed like a perfectly good goal refused two minutes after their opener when the referee decided the ball had gone out of play just before Emana had beat Landreau.

Toulouse coach Elie Baup believed that decision threw a spanner in the works.

"Refusing us that goal was the turning point because we would have been much better placed for the rest of the match," said Baup.

"I don't see what was wrong with it. But we have to just keep going and keep our heads up in the next few matches."

PSG midfielder Jerome Rothen slid a superb through ball to Luyindula just after the half-hour mark, the Frenchman beating the off-side trap to level for PSG.

Edouard Cisse then handed the visitors a shock half-time lead after seeing his 20-yard take a slight deflection to land in the top corner of Nicolas Douchez's net.

Luyindula was sent off for a second bookable offence nine minutes before the final whistle, but despite their handicap PSG battled till the end and were rewarded with a third goal from Rothen in the third minute of injury time.

"We would have quite happily settled for a draw," said the midfielder.

"So you can imagine how (happy) we feel, even though, mathematically, we're still not safe from the drop."

Lyon meanwhile finally had the pleasure of showing off their sixth consecutive league trophy to their home fans after a 2-1 win over Le Mans.

At the other end of the table, the future is looking decidedly down for former champions Nantes, who suffered a 2-0 home defeat to stay rooted to the bottom of the table.

With four games remaining the 'Canaries' are five points behind third-from-bottom Troyes and a point behind Sedan.
