The Frenchman has said he will remain at Lyon for at least one more year, in light of reports he could leave following the club's drop into the Europa League
Lyon entered the Europa League after Remi Garde's men were humbled 4-0 on aggregate by Real Sociedad in the Champions League play-off, prompting speculation that potential suitors could rekindle their interest in the Frenchman.
The 22-year-old was heavily linked with a move to Premier League outfit Arsenal earlier in the summer but, with days to go in the transfer window, Grenier - whose contract expires in 2016 - has ruled out a last-minute departure from Stade de Gerland.
He told RMC Sport: "There is no question to ask. I will stay at least one more season.
"It will be complicated [when I want to leave], but then I must ask the president [Jean-Michel Aulas]. But I am happy in Lyon."
Grenier initially put the rumours regarding his future to bed by signing a two-year contract extension in July with the French giants.
