Depay on target as Lyon beat Rennes; Troyes hand Nice second-straight loss
Lyon held on to win their second match in as many tries in Ligue 1 this season with a 2-1 victory at Rennes.
Bruno Genesio's side struck twice in the second half through Memphis Depay and Mariano to open up a 2-0 lead and survived an anxious finale after Benjamin Bourigeaud's late free kick reduced the deficit.
Former Manchester United forward Depay struck direct from a free kick to break the deadlock for Lyon soon after the break and striker Mariano notched his third goal in two games when he headed home their second in the 74th minute.
Rennes, who drew 1-1 at Troyes in their opening game, were given brief hope when Bourigeaud fired home a low free kick in the 86th minute, but Lyon stood firm to maintain momentum after last week's 4-0 home win against Strasbourg.
Saif-Eddine Khaoui's late winner sank Nice as newly-promoted Troyes secured a shock 2-1 win against the Champions League hopefuls.
Tunisian midfielder Khaoui struck the decisive goal in the 85th minute after Alassane Plea's second-half penalty appeared to have rescued a point for Nice by cancelling out Adama Niane's brilliant strike for the visitors.
Nice, who travel to Napoli on Tuesday for the first leg of their Champions League second-round qualifying tie, are left waiting for their first league points after last week's opening-day defeat at St Etienne.
Troyes took the lead in style through Niane's thunderbolt eight minutes into the second period.
Plea equalised from the spot 10 minutes later after Oswaldo Vizcarrondo's foul on Pierre Lees-Melou, but Khaoui steered home the winner after being set up by Niane.
