Lyon opened the defence of their Ligue 1 title with a 1-0 victory over Auxerre.
Hunting a seventh successive triumph in France, and first under new boss Alain Perrin, Lyon were quickly into their stride.
Milan Baros struck in the 32nd minute and Lyon's advantage was doubled when Karim Benzema fired home after 70 minutes.
Auxerre kept resisting strongly but could not claw back a goal to put pressure on the champions in the dying stages.
In the day's earlier game, Metz began life back in the top flight with a 1-0 defeat at Le Mans.
Marko Basa grabbed the crucial goal in the 27th minute and Le Mans held on to secure all three points.
