OL reacted well after their disappointment in Nice.
At home, the Gones won on the smallest of the margins against RC Lens (2-1).
Led by a Houssem Aouar of the great evenings, the Rhodaniens opened the scoring on a penalty converted by Karl Toko-Ekambi (25th) before Aouar gave a more substantial advantage to his head before the break (41st).

An advantage of two happy goals for the band to Peter Bosz, who took advantage of the offside of Jonathan Clauss, who believed he had equalized earlier (33rd).
It was finally Arnaud Kalimuendo, on loan from PSG, who reduced the mark after returning from the locker room after a nice movement with Gaël Kakuta (61st).
Insufficient however for Lensois hardly paid for their debauchery of energy.
Franck Haise's troop remains provisionally second but is exposed to Nice, which moves to Angers on Sunday (1 p.m.).
For its part, OL are temporarily back to 5th place, overtaking Rennes, to which they will travel next Sunday (8:45 p.m.).
In the meantime, the two teams will be engaged on the European scene, with the receptions of Sparta Prague for OL and Slovenes of Mura for the Bretons on Thursday.
