Rennes had to settle for a 1-1 draw at home to struggling Troyes.The visitors, without a win in Ligue 1 this season, went ahead against the run of play through Jessy Pi's 11th-minute volley.Rennes remain unbeaten since the opening day of the campaign and always looked like getting an equalising goal. It came after 71 minutes when Fallou Diagne got to a cross ahead of goalkeeper Denis Petric to head the ball into an empty net.Clinton N'Jie wanted a penalty late on after feeling his shirt was being pulled inside the area and as frustration boiled over, Yacouba Sylla was sent off in injury time following a second yellow card.ends
