Toulouse remain deep in relegation trouble in Ligue 1 after losing 2-1 to fellow strugglers Guingamp.The away side took the lead after 12 minutes, Younousse Sankhare scoring from six yards after good play from Yannis Salibur and Jimmy Briand.The lead lasted until midway through the second half when Toulouse equalised through a Wissam Ben Yedder penalty after a handball by Jeremy Sorbon.Guingamp were not to be denied, though, as 18 minutes from time Briand finished a flowing move with a precise finish into the bottom corner.Toulouse's misery was complete when Issa Diop was sent off for a second yellow card in injury time.
