The 48-year-old praised his side for their performance against the Italian champions but does not thnk they have much chance of turning their Europa League tie around in Turin
The Ligue 1 side were just six minutes away from holding the Italian champions to what would have been a fine goalless draw in their Europa League quarter-final first-leg clash at the Stade de Gerland when Leonardo Bonucci struck.
"We tried to compete with a great team. We came very close to what we wanted and were almost in a strong position heading to Turin,” Garde told Bein Sports.
“But the second half was harder than the first and every attack became more difficult to deal with.
“I obviously regret that we have conceded from a set piece. This is a very high level and matches are decided by the smallest details but I am still very happy by what was done by my youngsters."
Garde admits his charges are now massive underdogs to reach the last four of the competition.
“We are disappointed, but we knew before the game that Juventus are one of the best teams in Europe, so it was a mountain to climb," he mused. "Now I think we need a miracle to score two goals in the second leg.
“We had the best scoring opportunities of the first half, but it is difficult to succeed at this level if you do not take your chances.
“It has been a great experience for my young players; like playing 100 games in one."
