Francis Gillot's reign as Bordeaux coach got off to a losing start as Les Girondins went down 2-1 at home to St Etienne in their Ligue 1 opener.
Bordeaux, the 2009 champions, were on the back foot early on and were 2-0 down at half-time thanks to Michael Ciani's own goal and a Pierre-Emerick Aubameyang strike. Jussie halved the deficit from the penalty spot 11 minutes after the interval but Bordeaux could not force an equaliser.
Newly-promoted Dijon were given a harsh lesson in what lies in store in Ligue 1 as Rennes ran riot in a 5-1 victory at the Stade Gaston Gerard.
Victor Montano and Julian Feret put the visitors 2-0 up after the latter had missed an earlier penalty, but Brice Jovial halved the deficit before half-time. Abdoulrazak Boukari restored the two-goal cushion and, after Dijon's Gregory Thil also failed from the spot, Kader Mangane and Alexander Tettey completed the rout.
