Following their heaviest Ligue 1 defeat since February 2000, Garde has revealed that he was disturbed by the attitude of his players and conceded that without a change of fortunes he is unlikely to keep his job.
He told ESPN: "It's very clear that I'm in danger. It's wholly insufficient to win just once in our last ten matches. So I don't see why I wouldn't feel in danger.
"It's tough. I saw a completely crushed dressing room. I dare to imagine the players are in the same state as me.
"The final result is harsh, but the attitude and behaviour was quite disturbing. I'm going to talk about it with them."
The 47-year-old is in his third season in charge at Lyon, after the club chose to appoint from within when they replaced Claude Puel in 2011.
