Nantes came from behind to win their first Ligue 1 game at home since October with a 2-1 defeat of St Etienne.Les Verts broke the deadlock just before the quarter hour mark after Romain Hamouma went down inside the penalty area under a Remy Riou challenge, with Nolan Roux despatching the resulting penalty.Les Canaris hit back and, after hitting the post with an initial effort, Johan Audel levelled from close range following Yacine Bammou's pass.The hosts completed the turnaround with six minutes left to play when Florentin Pogba's good work gifted Kolbeinn Sigthorsson with an opportunity he took with aplomb to gain all three points.
