Paris Saint-Germain can provide further proof of the growing gulf in class between the champions elect and the rest of Ligue 1 when they travel to last year's runners-up Lyon on Sunday.

A fourth straight French league crown is well within sight for PSG, who could conceivably wrap up the championship next weekend, while Lyon's turbulent campaign has rendered last year's title challenge a distant memory.

Laurent Blanc's runaway leaders are unbeaten in 36 matches in Ligue 1 dating back to last March, whereas Lyon have suffered 10 defeats -- three more than all of last season -- and find themselves embroiled in a congested scrap for Europe.

PSG have beaten Lyon three times already this term, a crushing 5-1 win at the Parc des Princes in December was followed up by further triumphs in both domestic cup competitions, but OL will hope to maintain an unbeaten record in their new 60,000-seater fortress.

Since moving into the Parc OL in January, Bruno Genesio's side have registered three wins out of four at home, with their lone dropped points coming in a 1-1 draw with Marseille.

However, last Sunday's 1-0 defeat at Lille not only snapped a run of three successive victories but also left Lyon without midfielder Clement Grenier and former PSG defender Christophe Jallet for this weekend's clash after the pair were sent off to compound a miserable evening up north.

"We had the chance to go third and not only did we fail to do that, we also lost two players who will be suspended against Paris so we're paying a heavy price," said Genesio, whose side trail PSG by a staggering 34 points.

"That handicaps us even more against Paris, when that was the last thing we needed."

Monaco can take another stride towards claiming the second automatic Champions League berth when they travel to Nantes.

Leonardo Jardim's side are eight points clear of Nice and Saint-Etienne, but will face an in-form Nantes outfit unbeaten in 15 matches in all competitions.

"We're very happy. There are still 11 games to go, and we have to hold on to second place," Monaco vice-president Vadim Vasilyev told RMC radio.

"The most important thing is always the league table. The goal is to be in the Champions League next season, it's vital."

Bastia fans will be banned from Friday's trip to third-place Nice after recent violence, which prompted last weekend's game at home to Nantes to be postponed.

Fourth-place Saint-Etienne are at home to Caen on Sunday, while Marseille, with just two wins in 11 league outings, visit a Gazelec Ajaccio side chasing a first win in nine.
