Nantes left it very late to seal a 1-0 win against Guingamp in their opening Ligue 1 game of the season.Jeremy Sorbon's 89th-minute own goal was enough to decide a drab encounter as Les Canaris secured a fortunate three points.Brazilian Adryan had an impressive debut for the hosts and was at the centre of most of their good work, but the former Leeds forward failed to breach a resolute Guingamp defence.But, with less than a minute to play, Johan Audel's dangerous-looking cross was inadvertently turned beyond his own goalkeeper by Sorbon to hand all three points to Michel Der Zakarian's men.
