Marseille, France (SportsNetwork.com) - First meets third on Sunday when Ligue 1 leaders Lyon hit the road to face Marseille at the Stade Velodrome in an important battle at the top of the league.

Marseille got back on track after a four-game winless run by thrashing Toulouse, 6-1, last Friday, while Lyon also turned in a resounding performance over the weekend by hammering Montpellier, 5-1.

Marcelo Bielsa's Marseille can cut its deficit to just one point with a win over Lyon, which won the first meeting between the two sides, 1-0, through a goal from Yoann Gourcuff.

Gourcuff will take no part in Sunday's clash because of a thigh injury, but the game will feature the top two scorers in Ligue 1 as Lyon's Alexandre Lacazette brings his 23 goals into the contest and Andre-Pierre Gignac of Marseille looks to add to his total of 16.

Second-place PSG sits one point back of Lyon and the club travels to Bordeaux with the hope of taking over first place with a win.

PSG's upset of Chelsea in the Champions League in midweek will give Laurent Blanc's side even more confidence as the team attempts to extend its unbeaten streak in league play to nine games.

Fourth-place Monaco moved to within three points of a spot in the top three on Friday as Anthony Martial scored a goal in each half to lead the club to a 3-0 win over Bastia, which finished the match with nine men.

Also on Friday, Christophe Mandanne scored a pair of goals in the second half to lead Guingamp to a 2-1 win at Nice, which remains five points above the relegation places.

St Etienne hopes to improve its prospects of qualifying for a European place with a win at last-place Metz and two of the bottom three teams in the league square off when Lens faces Toulouse.

Lens has lost its last four games and is nine points from safety. Toulouse is in a better position sitting two points from 17th place despite losing three of its last five games.

Lorient resides just above Toulouse and will host Caen, Reims visits Montpellier, Nantes tangles with Evian and Lille squares off with Rennes.
