PSG opened up an eight-point lead with their 4-0 Classique hammering of OM, while OL got a first win under new boss Rudi Garcia and Ligue 1 Conforama top scorer Wissam Ben Yedder hit his ninth in as many matches for Monaco.
Despite a wash of injuries to key players in the early stages of the season - Neymar, Edinson Cavani and Kylian Mbappé chief among them - Paris Saint-Germain are looking more than ever to be candidates for their own succession as Ligue 1 Conforama champions following a comprehensive 4-0 beating of arch-rivals OM at the Parc des Princes on Sunday night.
Icardi: 'Two goals in my first Classique'
Although Marseille mixed it with their hosts in the opening ten minutes, André Villas-Boas' side were caught out by the clinical finishing of Mauro Icardi - whose two goals took him to seven in his last five appearance in all competitions - and the pace and precision of Mbappé, who also bagged two in the capital club's first-half goal blitz.
"I felt really good tonight. I scored two goals in my first Classique - more than I could have hoped for. We won this big match in style and that's the most important thing. Four-nil is a great scoreline and we need to keep working hard to continue getting results like this," said Icardi, who also struck a double in PSG's 5-0 Champions League drubbing of Bruges, a performance that saw him start ahead of a fit-again substitute Cavani. "Angel Di Maria supplied me with two great passes to try and score and at the end of the match and we had a good moment with the supporters to celebrate the match together. It was fantastic."
OL back on track
While PSG were busy putting daylight between them and their chasers, Olympique Lyonnais set about putting a stop to the club's worst run of form in decades as Memphis Depay hit his fifth of the season - and drew the penalty converted by Moussa Dembélé - to clinch a 2-0 win over FC Metz.
"This was a crucial victory and I liked my players' attitude. They controlled the match. It was a very good first half with two goals," said coach Rudi Garcia, tasting victory with his new club for the first time after drawing 0-0 with Dijon and losing 2-1 away to Benfica in mid-week. "The team gelled well. [Anthony] Lopes kept a clean sheet and made some important saves. Everyone played well. It's a message to the squad that I'm counting on them all."
Ben Yedder breaks Nantes
The win took OL from the brink of the relegation zone to 13th, just two points shy of AS Monaco, who climbed to 11ththanks to Ligue 1 Conforama top scorer Wissam Ben Yedder's ninth of the season. The France international has been banging home the goals since his move from Sevilla and not even second-placed Nantes - who hadn’t conceded at the Stade de la Beaujoire all season - could stop his deadly finishing and avoid a 1-0 defeat.
"It's important to win away from home. In our position, we have to take points home and away," said Monaco boss Leonardo Jardim, for whom this first away win of the season is the club's fourth victory in their last five outings. "It was a tough game against a good team. The whole team defended well and showed character. We have to keep working to continue winning."
André sparks LOSC, Stéphan breathing easier
The defeat - a second in a row for Christian Gourcuff's side - sees Nantes stay in second but now with just a one-point lead over LOSC, who blasted back into form with a 3-0 win over Bordeaux that was kicked off by Benjamin André's superb maiden strike since his summer move from Rennes. Injuries to club captain José Fonte and goal sensation Victor Osimhen could prove expensive as Christophe Galtier's side head into a month of November featuring clashes with OM, PSG, Valencia and Ajax.
Under-pressure Rennes coach Julien Stéphan is breathing a bit easier after his side prevailed in a five-goal thriller at home to a Toulouse side looking rejuvenated under new boss Antoine Kombouaré. A last-gasp strike from 18-year-old Yann Gboho, making his second Ligue 1 Conforama appearance, clinched it 3-2 for Rennes, breaking a ten-match winless run and taking the club ninth.
Reims held as Brest fire
In-form Reims, who have lost just three times this season while also claiming the scalps of OM, PSG and LOSC, had a chance to go second as they played host to Nîmes, but their 0-0 draw saw their lead over fifth-placed Brest cut to one point. The promoted Brittany club kept Dijon rooted to the foot of the table with a 2-0 win courtesy of a Paul Lasne screamer and Denys Bain's first Ligue 1 Conforama strike (which was followed by his first Ligue 1 Conforama red card).
Saint-Etienne maintained their unbeaten form under new boss Claude Puel but only just, with Amiens' Bakaye Dibassy turning into his own net with ten minutes to go in the 2- draw, while mid-table Montpellier and Angers played out a scoreless draw on the south-west.
Strasbourg pulled themselves off the foot of the table with a first win in three matches, 1-0 at home to out-of-sorts Nice courtesy of Adrien Thomasson.
