The big spending Parisians fell to a goal from Julien Quercia, in an ironic twist after the Qatari owned club signed Lorient’s top scorer last season, Kevin Gameiro.
In a further irony, Lyon, who have not spent a penny on major signings this summer, were the only pre-season title favourite to win after Marseille could only draw 2-2 at home to Sochaux and champions Lille drew 1-1 at Nancy.
Lyon won 3-1 at Nice.
