PARIS, Feb 10 (Reuters) - Olympique Marseille handed Nice their first home defeat of the season with a 2-0 win in their Mediterranean derby in Ligue 1 on Sunday.
Senegal striker Mamadou Niang, back from the African Nations Cup, opened the scoring in the first half and France forward Djibril Cisse doubled the advantage after the break.
Marseille, who have scored 11 goals in their last three matches, climb to fifth in the 20-strong league. Nice stay fourth but drop 12 points behind leaders Olympique Lyon.
Strugglers Racing Lens moved up to 13th with a 4-1 win at Caen earlier on Sunday, forward Toifilou Maoulida showing the northerners the way with the quickest goal in Ligue 1 this season, a header after 16 seconds.
Two goals from midfielder Mathieu Bodmer had helped Lyon crush strugglers Sochaux 4-1 on Saturday to stay four points clear at the top.
Lyon, chasing a seventh consecutive title, have 49 points from 24 matches. Second-placed Girondins Bordeaux beat bottom club Metz 3-0 with two goals from Fernando Cavenaghi.
Third-placed Nancy, who had gone nine league matches without a win, beat Toulouse 1-0 with a late penalty from defender Sebastien Puygrenier, also on Saturday, to stay eight points off the pace.
