Marseille captain Steve Mandanda is delighted his side have their Champions League destiny in their own hands but has warned them not to take tomorrow's opponents Lorient lightly.
OM lie second in Ligue 1 with five games remaining, although they trail rivals Paris St Germain by nine points and have third-placed Lyon snapping at their heels just two points back.
Their success this season has been built on defensive strength, winning 18 games despite scoring only 37 goals. Eleven of those victories have come by a 1-0 scoreline, just one less than the Ligue 1 record held by PSG.
Mandanda himself has not conceded a goal in his last six appearances but he knows he will have his work cut out against a free-scoring Lorient side led by Jeremie Aliadiere, who opened the scoring in a 3-0 win at the Stade Velodrome in December.
Mandanda told reporters at a pre-match press conference: ``It will be hard, Lorient have always caused us problems. They play good football and going there is always difficult.
``They gave us a slap in the previous match but now it is a different context, having begun the final sprint.
``At this point of the season, nobody can afford to drop points. We have a slight advantage because we are in second place and we have our destiny in our own hands.''
Aliadiere, available after suffering a slight hip injury against Toulouse last time out, is the leading French goalscorer in Ligue 1 with 15 goals this season and has scored 11 in his last 12 games.
Lorient's defence remains severely weakened though, with Lamine Kone, Lucas Mareque, Arnaud Le Lan and Wesley Lautoa all absent. Midfielders Mathieu Coutadeur and Alain Traore and striker Julien Quercia also miss out, with Traore ruled out for the season.
Marseille, meanwhile, have a fully-fit squad to choose from at the Stade Yves-Allainmat, where Lorient have lost only once this season.
