Marseille came from behind to close the gap on leaders Lyon in Ligue 1 as they won a thrilling game against last year's champions Montpellier 3-2 after a late goal from Andre Pierre Gignac.
Marseille were left reeling when Andre Ayew's 15th-minute strike was immediately cancelled out by Emanuel Herrera before John Utaka gave Montpellier a shock lead just before the hour mark.
OM looked set for a second successive defeat - after a shock 3-1 loss against 10-man Sochaux last Sunday - but Jordan Ayew levelled proceedings in the 80th minute before Gignac completed the comeback in injury time.
Lorient moved into the top four after returning to winning ways but they were given a scare by struggling Troyes but still ran out 3-2 victors.
Christian Gourcuff's men have been one of the surprise packages this term and looked firmly on course for victory thanks to first-half goals from Kevin Monnet-Paquet and Enzo Reale.
They were pegged back by Jeremie Brechet after the hour mark and although Gregory Bourillon restored the hosts' two-goal lead, Fabien Camus set up a tense finale with two minutes left.
The resilient visitors could not find a leveller, however, and they remain second from bottom - seven points adrift of safety - while Lorient continue to defy the odds and are still firmly in the hunt for a Europa League spot next season.

Adrian Mutu had given the relegation-threatened hosts the lead on the half-hour mark and things got worse for VA after the interval when defender Benjamin Angoua was sent off for a tackle from behind on the Romanian.

Loic Poujol's close range goal gave Sochaux a 1-0 win over relegation rivals Reims - who remain without an away success this season.

Nancy's survival hopes receded even further as the basement boys went down 2-1 at Toulouse.
Franck Tabanou's second-half brace put the mid-table hosts in control and, although Lossemy Karaboue halved the deficit two minutes from time, it was too little too late. The loss means Nancy have still won just once in the league this season and are now eight points from safety.
