PARIS, April 12 (Reuters) - Olympique Marseille overtook Olympique Lyon at the top of Ligue 1 on Sunday after they beat Grenoble 4-1 and the seven-times champions only drew 2-2 at home to mid-table Monaco.

Lyon had topped the table after every round of matches since mid-September. They are now a point behind Marseille, who have 61, with seven games remaining.

Girondins Bordeaux, who beat AJ Auxerre 2-0 on Saturday, are third on 59.

The first goal that led to Lyon's downfall was scored in the 34th minute by Croatian midfielder Jerko Leko, who was perfectly set up by a backpass from South Korean Park Chu-young after a swift counter-attack.

Lyon's France striker Karim Benzema hit the woodwork five minutes later and the champions had another chance on the hour when Monaco keeper Stephane Ruffier blocked Jean Makoun's header.
