Rampant Bordeaux moved level on points with Marseille at the top of Ligue 1 as goals by Gregory Sertic, Yoann Gourcuff and Marouane Chamakh secured them a 3-0 win over struggling Sochaux at the Stade Chaban-Delmas.

Midfielders Sertic and Gourcuff struck in the opening 14 minutes to put Les Girondins in the box-seat and Chamakh grabbed the third deep into second-half stoppage time. Laurent Blanc's men are only behind OM on goal difference now, one goal separating the two sides who will battle it out for the title in the final four matches of the campaign.

Sochaux, who had Radiu Afolabi sent off late on for two bookable offences, stay 17th and just outside the relegation zone, although they are level on points with third-bottom Nantes.

Elsewhere, a Mamadou Sakho own goal prevented Paris St Germain from moving into the Champions League places as they lost 1-0 at home to Rennes.

PSG could have leap-frogged faltering champions Lyon into third position but they failed to make the most of their opportunity, Sakho inadvertently turning Jerome Leroy's shot into his own net in the 65th minute to settle a dull match the visitors' way. The win keeps Rennes' European ambitions alive as they now sit six points behind PSG.

Finally, Le Havre staved off relegation - for 10 days at least - with a come-from-behind 2-1 victory at fellow relegation battlers Nantes. Christian Bekamenga put the hosts ahead midway through the first half but Mamadou Diallo restored parity six minutes before the interval and then Florian Marange struck the winner just after the hour.

The victory will surely provide only a stay of execution for the Normandy club, who have been teetering on the brink for a while now and remain nine points adrift at the bottom.
