Paris St Germain were the only winners as Lyon and Marseille played out a dull goalless draw at the Stade Gerland on Sunday evening.
Carlo Ancelotti's table-topping side are now four points clear of Lyon and seven ahead of Marseille following their 2-1 win over Nancy yesterday with just 10 rounds remaining in the Ligue 1 title race.
OM's Andre-Pierre Gignac came closest to a goal with a 10th-minute shot which lashed inches wide but there was little for either set of fans to get excited about.
Stephane Bahoken marked his first start in Ligue 1 with a first-half brace against Montpellier to lift Nice to fifth with a 2-0 home win.
Bahoken scored from close range in the 12th minute and again in the 24th as his side bounced back in style from last week's 4-0 defeat to St Etienne.
Montpellier pressed in the second half and hit the woodwork through Younes Belhanda, but the reigning champions could not find a way back into the game.
Cheick Diabate scored the only goal as Bordeaux ended a four-match losing run in Ligue 1 with a 1-0 win that put the pressure back on struggling Bastia.
It was one-way traffic at the Stade Chaban-Delmas and, after Ludovic Obraniak had struck the crossbar, Diabate grabbed the opener having come off the bench for the start of the second half.
The win lifts Bordeaux one place to ninth, while Bastia remain just three points above the drop zone.
