The Messins are three points behind Sochaux (2nd) and Bordeaux (3rd), 39 points both, while Le Havre, although hung 0-0 at home by Paris-FC on Friday, still prances in the lead with eight steps ahead.
Conversely, Amiens, which had held Bordeaux and Le Havre in check recently, is now six points behind second place.
The first period was generally dominated by the Picards even if the young left-back of ASC Kassoum Ouattara (18) almost scored against his side.
The player, who turned professional last summer, took over an aerial cross with a header, but the ball hit a post before being recovered by goalkeeper Régis Gurtner (21st).
A few minutes later, Mamadou Doums Fofana took his chance with a direct free kick from 30 meters,

The Garnets reacted by taking advantage of a ball lost by Nicholas Opoku and recovered by Georges Mikautadze, who served Cheick Sabaly with a ladle in the area, but the Senegalese striker could not frame his volley (38th) .
Unable as often this season to be realistic (only 1 shot on target), the Amiens ended up being punished by the Messins.
Illicitly tackled in the area by Opoku, Mikautadze obtained a penalty which he transformed into a full center force (1-0, 55th).
This is the eleventh goal of the Franco-Georgian this season in L2, which joins the Bordelais Josh Maja at the top of the scoring charts.
He was also behind the second goal.
His corner, however not very well hit, was magnificently taken over by the young Arthur Atta (20 years old), with a cross volley, returning post (2-0, 78th).
Sabaly almost added a third goal with a wrapped shot, but the post this time saved Gurtner (87th).
