Marseille forward Loic Remy believes his side can turn up the pressure on Lille in the Ligue 1 title chase with their rivals not playing in the league this weekend.
Marseille travel to Lorient on Sunday evening knowing victory would move them to within a single point of table-topping Lille, who face Paris St Germain in Saturday's Coupe de France final and thus are not in league action until Wednesday against Sochaux.
And Remy, who opened the scoring in Wednesday night's 3-0 win over Brest, told om.net: "We have the advantage of playing first. On Sunday, we have to make sure we win. We know that if we win this weekend, we will move within a point having played a game more."
Remy was signed from Nice early in the season and experienced Lorient's artificial pitch with his former employers, for whom he scored in a 2-1 win at the Stade Yves Allainmat in week two of the season.
But he warned: "It's always to difficult to play on the synthetic pitch. With Nice, I played at Lorient at the start of the season - it is very fast, it's not pleasant."
Third-placed Lyon travel to Brest on Monday, and victory would lift OM nine points clear of Les Gones, who would have only three games to play and whose goal difference is currently inferior by four after Wednesday night's hammering by Auxerre.
Coach Claude Puel told OLTV: "We have managed to relax at home; now we must do the same away from home, starting at Brest."
Referring to Sunday's 3-2 win over Marseille, he added: "We have shown many faces recently; now we must show the same as against OM."
At the other end of the table, Lens will be condemned to relegation should they fail to beat 17th-placed Monaco, who lie six points ahead of them with a superior goal difference.
Monaco coach Laurent Banide knows the importance of the game for his side, who lost 3-0 at Sochaux on Wednesday, and said: "We have three very important games remaining, starting with Lens on Sunday which has become a huge match."
Nancy, who occupy the third and final relegation place - with Arles long since condemned - host 14th-placed Nice looking to eat into a four-point gap, while 16th-placed Caen take on Montpellier.
Rennes, in fifth, travel to St Etienne and Toulouse visit Arles, while PSG face Bordeaux in the other Wednesday game.
