Unai Emery remained confident that Paris Saint-Germain can win the Champions League in the future after his team crashed out in the round of 16 with a defeat to Real Madrid on Tuesday.
Despite massive spending since Qatar Sports Investments bought the club, PSG have not advanced past the quarterfinals in Europe's elite club competition in the past six seasons.
Under Emery, PSG have now exited in the round of 16 two years in a row, but the manager said the club's future remains bright.
"We all want to win this competition quickly. We'll continue with patience, and build a team that can win," he said.
"I'm sure this team can win the Champions League. The supporters will see that Paris will win this competition one day.
"Losing to Madrid is not a disappointment, but going out in the last 16 is. But, the first leg was the key because we were better over the first 80 minutes than them.
"They controlled 60 percent of this match and we couldn't do enough in the 40 percent we controlled."
Whether Emery remains with PSG to obtain that future goal remains to be seen, but president Nasser Al-Khelaifi said no decision would be made immediately.
"It's not the moment. Everyone is very upset," he said, according to L'Equipe. "We will calm down to think about what to change."
Al-Khelaifi said the PSG ownership was not pleased with the effort given by some of the players.
"The elimination, the reaction of some players," he said when asked what the biggest disappointment was. "We are not happy at all. We are very, very disappointed with the result.
"In the first half we dominated. We were only missing a goal, that's all. With one goal the match would have changed.
"[Marco] Verratti's red card killed the match. We will work, give more for the club and our supporters."
Midfielder Adrien Rabiot expressed his regrets to the PSG fans after the club lost their first game at the Parc des Princes in any competition in nearly two years.
"Our fans got behind us, I apologise to them," Rabiot said. "We tried but we couldn't do it."
