Guingamp secured a third successive league win with a comprehensive 4-0 defeat of Ligue 1's bottom club, Troyes.The hosts took the lead in the sixth minute when Jonathan Martins Pereira released Mevlut Erding and the Turkey international slid the ball between Matthieu Dreyer's legs.And Guingamp doubled their lead just after the interval when Erding saw his shot saved before Jimmy Briand teed up Younousse Sankhare from the rebound.All three points were made sure of 10 minutes later thanks to a clinical Thibaut Giresse finish from just inside the area, before Ludovic Blas netted his first ever Ligue 1 goal as added time approached.
