Montpellier came from behind to claim a fifth home win in six with a 2-1 defeat of 10-man Guingamp.The visitors were first to make the breakthrough as Sloan Privat headed beyond Laurent Pionnier on 33 minutes before their evening took a rapid turn for the worse when Nicolas Benezet was given his marching orders moments later.And that dismissal proved costly as La Paillaide levelled just after the break when Souleymane Camara smahed a header beyond Jonas Lossl from Ryad Boudebouz's perfect delivery.The turnaround was complete on 61 minutes when Jerome Roussillon and Camara combined to tee up Rodrigue Ninga for his fifth goal in four games.
