Guingamp continued their impressive start to the new Ligue 1 season with a 2-0 win at Nancy, although they rode their luck at times.Second-half goals from Mustapha Diallo and Thibault Giresse settled the contest as Guingamp moved on to seven points from three games, having started the campaign with a draw at Monaco and win over Marseille.Nancy are still looking for their first goal and first points, but they can consider themselves unfortunate to have ended Saturday's game empty-handed after hitting the crossbar three times - through Loic Puyo, Benoit Pedretti and Christophe Mandanne - as well as seeing Youssouf Hadji fire a late penalty wide.ends
