Despite Pascal Delhommeau earning an early bath minutes later, the side added a late third through Stephane Ziani to clinch a gutsy win.

The points had looked set to be shared after Jean-Claude Darcheville equalised Lamine Diatta's goal after 24 minutes, only for Feindouno to nick the win.
Daniel Cousin's strike for Le Mans had looked the match-winner for almost 45 minutes, before Eduardo Da Silva's last-gasp equaliser rescued a 1-1 draw for Toulouse.
