MARSEILLE, May 17 (Ligue 1) - Marseille clinched a Champions League place in dramatic fashion after Djibril Cisse's late strike earned a narrow win over Strasbourg on the last day of the Ligue 1 season on Saturday.
The win, coupled with defeat for Nancy at home to Rennes, means Marseille snatch third spot and a place in Europe's elite club competition.
Mamadou Niang put the hosts ahead in the sixth minute but James Fanchone and Kevin Gameiro scored for Strasbourg to turn the scoreline on its head.
In a dramatic spell on the stroke of half-time, Cisse equalised with a penalty and Nasri put Marseille in front a minute later.
Simon Zenke looked to have earned a draw with his 72nd-minute strike but Cisse made sure of the victory six minutes later.
Needing a win and a favour from Rennes, OM made a flying start at the Stade Velodrome.
They could have taken the lead in the third minute but Mathieu Valbuena's shot from the right hit the top of the crossbar.
Niang had already forced a good save from Strasbourg goalkeeper Stephane Cassard when he collected Nasri's cross and fired a low shot into the right corner.
The visitors levelled in the 10th minute when Fanchone latched on to a through-ball and beat Steve Mandanda with a well placed shot, and they took a surprise lead eight minutes later as Gameiro made a slick exchange with Eric Mouloungui before dispatching a shot from close range.
Taye Taiwo had a header cleared off the line by Zoltan Szelesi on the half-hour mark but the equaliser arrived when Strasbourg's substitute keeper Nicolas Puydebois brought down Cisse in the area. The striker's spot-kick was saved but he scored the rebound with a brave header.
In the fourth minute of first-half stoppage time, Elliott Grandin's superb cross found Nasri, who unleashed an unstoppable volley past Puydebois.
Strasbourg drew level late on when Zenke scored from close range after his initial effort had been saved by Mandanda, but the visitors' joy was shortlived as Cisse soon equalised after going one on one with Puydebois.
Marseille could have added a fifth when they were awarded another penalty for Pierre Ducrocq's foul on Kanga Akale but Puydebois thwarted Modeste M'Bami.
