Florian Raspentino's late goal grabbed a vital three points for out-of-sorts Bastia as they defeated Bordeaux 1-0 in Ligue 1, heaping pressure on Les Girondins boss Willy Sagnol.It looked like an uninspiring encounter at the Stade Armand-Cesari was heading for a goalless draw until substitute Ilias Hassani's slip gifted opportunist Raspentino with an 88th minute winner.Bastia had created the best opportunities in the second half, with Brandao and Floyd Ayite both being wasteful in front of goal, and in the end the toothless visitors could have little to argue about.Defeat for Bordeaux stretched an unwanted record of 12 games without a win away from home.
