Les Gones have slipped into the bottom half of Ligue 1 after a dreadful run of form, but Garde believes that his squad are quick learners and can meet the demands of playing three times a week.
He told Ligue 1's official website: "We picked up where we left off after equalising in injury time against Bordeaux on Sunday. The result is a real relief for our young squad.
"A lot of my players are discovering the demands that European football places on a squad. It's fast-tracking their development and the squad is maturing as a result.
"There were some absences tonight and the replacements seized their chance; the concentration and team spirit was excellent. We gave our very best and we're very satisfied."
Lyon's return to Ligue 1 action this weekend promises to be a stern test of their recent recovery, when they face unbeaten Monaco on Sunday night.
