The dismissal of Bordeaux goalkeeper Ulrich Rame after 31 minutes was the turning point in a thrilling game at Parc des Princes.

Rame saw red for handling the ball outside his area and PSG capitalised when Sylvain Armand opened the scoring from the resulting free-kick.

Mevlut Erding doubled the lead 16 minutes from time before Bordeaux reduced the deficit through Ludovic Sane.

Guillaume Hoarau netted PSG's third late on to put the result beyond doubt, as fifth-placed Bordeaux slumped to a defeat that leaves them three points behind leaders Marseille having now played the same number of games.

Fellow challengers Montpellier did only marginally better as they took just one point from a bad-tempered 2-2 draw at Le Mans.

The surprise challengers were a goal down within a minute of kick-off through Roland Lamah, but Karim Ait Fana levelled 10 minutes later.

Souleymane Camara put Montpellier ahead from the spot after 33 minutes, but Cyril Jeunechamp was sent off for the visitors - extraordinarily for attacking Le Mans coach Arnaud Cormier - and Gregory Cerdan for the hosts followed moments later.

Montpellier coach Rene Girard was also sent to the stands and Lamah struck again for Le Mans in the second half to claim a point.

Grenoble's relegation to Ligue 2 was confirmed by their 4-0 defeat at Toulouse and St Etienne's 2-0 victory at Sochaux.

Paulo Machado opened the scoring for TFC after nine minutes and a second-half brace by substitute Franck Tabanou sealed Grenoble's fate before Andre-Pierre Gignac dealt a further blow five minutes from time.

St Etienne's win at Sochaux left Mecha Bazdarevic's bottom-placed side 20 points adrift of safety with six games remaining of the Ligue 1 campaign.

St Etienne got it done with goals from Loic Perrin and Gonzalo Bergessio in either half, moving them 11 points clear of relegation.

Toifilou Maoulida's hat-trick earned Lens an emphatic 3-0 home win which nudges Boulogne one step closer to the Ligue 1 relegation trapdoor.

The striker opened the scoring two minutes after Boulogne had hit the post through Olivier Kapo.

And he added two more after the interval to lift his team 14 points clear of the final relegation spot, occupied by their opponents.

Honours were even in the Breton derby as Lorient and Rennes drew 1-1, meaning neither side gained the win which might have enhanced their hopes of Europa League qualification.

Lorient briefly looked set to leapfrog their visitors when midfielder Sigamary Diarra's accomplished finish gave them an early lead, but Rennes hit back three minutes before the break through Romain Danze.

Monaco opened up a five-point advantage over 10th-placed Valenciennes as they came from behind to win the battle of mid-table teams 2-1.

Milan Bisevac's 36th-minute goal gave the visitors a half-time lead, but Nene's rocket levelled the match on the hour mark and Moussa Maazou got the winner 13 minutes from time.
