In a week of surprising results in France, both title challengers failed to pick up maximum points, with all but one side in the bottom half unbeaten over the weekend
Olympique de Marseille's slim hopes of the Ligue 1 title appear to be over once more, after they were held to a 0-0 draw against Ajaccio on Friday.
Elie Baup's side have been criticised for not taking advantage of Paris Saint-Germain's slip-ups, and even their grip on third place, and the final Champions League spot appears to be in the balance now.
The Corsican side have goalkeeper Guillermo Ochoa to thank, with the Mexico international thwarting the likes of Andre-Pierre Gignac and Jordan Ayew on various occasions.
Despite the barrage of attacking intensity from the hosts, Ajaccio did conjure up chances of their own, as Johan Cavalli lashed a shot inches wide of Steve Mandanda's post.
Ochoa denied Modou Sougou with a save off the line, as Ajaccio held on to claim a well-earned point at Stade Velodrome.
BASTIA 4-1 OLYMPIQUE LYONNAIS
Lyon's title hopes were also dealt a severe blow when they were soundly beaten by struggling Bastia at the Stade Armand Cesari.
The hosts welcomed back a number of their players following the melee which marred the Corsican derby against Ajaccio two weeks ago, and the impact was telling as Lyon's young stars were overawed.
The returning young star Florian Thauvin fired the Corsicans into the lead, before Lisandro Lopez equalised soon after.
Parity lasted just two minutes, before Wahbi Khazri picked out Anthony Modeste for his first goal in eight games. Further goals from Thauvin and Khazri in the 87th minute sealed a huge win for Frederic Hantz's side.
LORIENT 4-0 STADE BRESTOIS
Lorient turned on the style to demolish Stade Brestois 4-0 at Stade du Moustoir on Saturday evening, to move up to eighth.
Three first-half goals sealed victory for the hosts, who have rallied following three games without a victory to keep up their pursuit of a European spot as Brest became the only side in the bottom half of the table to fail to score a point.
Julien Quercia broke the deadlock inside three minutes, before Yann Jouffre doubled the Merlus' advantage just five minutes later as the hosts hit the ground running.
Wesley Lautoa directed in a third just before the break, as the visitors failed to stem the flow of goals in an otherwise disappointing first half performance. Gilles Sunu wrapped up the win on 81 minutes to seal a big win for Christian Gourcuff's side.
SOCHAUX 1-1 VALENCIENNES
Sochaux followed up their heavy 5-1 defeat to Evian last weekend with a frustrating 1-1 draw against mid-table Valenciennes at Stade Bonal.
Ryad Boudebouz fired the hosts in front after eight minutes. Giovanni Sio's shot was parried by goalkeeper Nicolas Penneteau, allowing the Algeria international to power into an unguarded net.
Despite having chances, it wasn't until the 82nd minute that the visitors found the net. Gregory Poujol's fine pass picked out Opa Nguette and deny the hosts a much-needed victory.
LILLE 1-2 EVIAN
Lille's five-game winning streak in Ligue 1 ended on Saturday as they were beaten 2-1 by Evian, whose relegation fears have been eased considerably.
It started well for the northern side, with Salomon Kalou sending home Djibril Sidibe's cross from the right-hand side to fire LOSC in front.
Saber Khelifa equalised with a fine finish on the half-hour, before Kalou somehow turned into his own net after Djakaridja Kone's effort struck him in the face and bounced home as Evian fortuitously took the lead.
Nevertheless, Kalou could have made amends for the own-goal after being fouled by Kone inside the box, though his penalty was fired over the bar as Evian sealed victory.
MONTPELLIER 1-1 TROYES
Montpellier were denied a ninth straight home victory by a resurgent Troyes side who picked up a well-earned point at the Mosson.
Gaetan Charbonnier volleyed the hosts ahead early on, firing an angled effort past the outreached hands of Yohann Thuram-Ulien.
The champions were dominating early on, and should have had a second as John Utaka went close, before Hilton's header cannoned off the Troyes crossbar.
The relegation strugglers equalised though, as Marcos laid off Corentin Jean - the 17-year-old's third goal in two games - to seal a point.
STADE DE REIMS 1-0 STADE RENNAIS
Reims ensured that European challengers Rennes went five games without a win, claiming a 1-0 win over the Breton side.
Mohamed Fofana struck the game's only goal, as he ensured Frederic Antoinetti's 500th Ligue 1 game ended in defeat, with the Coupe de la Ligue finalists now dropping to ninth.
Reims, who now have three wins in the last six weeks, picked up a second home victory in a row, but could have been pegged back if Alou Diarra's shot which crashed off Kossi Agassa's post went in.
NANCY 1-0 NICE
Nancy closed the gap on 17th-placed Brest to just five points by pickig up a surprise 1-0 victory over Nice on Sunday at Stade Marcel Picot.
The bottom club in Ligue 1 were by far the most positive of the two teams, playing flowing football in the first half, which saw various chances created.
Thomas Mangani's effort curled agonisingly wide of the post, before Djamel Bakar powered in an opener for Patrick Gabriel's side on 23 minutes.
Nice rallied after the break, with Alexy Bosetti bringing out a fine save from Damien Gregorini, while at the other end, David Ospina was kept busy, thwarting Thomas Ayasse and Lossemy Karaboue, though Nancy held on - despite having two goals ruled out for offside.
TOULOUSE 0-0 BORDEAUX
Bordeaux's hopes of qualifying for next season's Europa League took another dent as they were held to a turgid 0-0 draw by south-western rivals Toulouse at Stadium Municipal.
The encounter itself was noticeably lacking in quality, with both defences holding strong as Toulouse picked up a fourth clean sheet in a row.
The visitors were lacking incisive power, despite their narrow Europa League exit to Benfica in midweek, they look unlikely to make next season's competition - as Francis Gillot's side remain in tenth position in the table, and TFC a place, and four points further adrift.
