Steve Clarke spoke of his pride after Scotland's first major tournament appearance in 23 years ended in a 3-1 defeat to Croatia.
But the 57-year-old also shared his belief that the disparity in tournament experience between the two sides was a decisive factor in the Scots exiting Euro 2020 at the group stage.
Having picked up just a point from their opening two games, both Scotland and Croatia needed a win at Hampden Park to secure a place in the round of 16.
And it was the visitors who got it, with Nikola Vlasic, Luka Modric and Ivan Perisic goals rendering a Callum McGregor equaliser - the first Scottish European Championship goal since Ally McCoist against Switzerland on June 18, 1996 - irrelevant.
Reflecting on the defeat, Clarke told ITV: "I'm proud of the players, the fact they managed to get here for the first time in 23 years, that was a big thing for the country, a big thing for this group of players.
"I think you saw tonight a team that's tournament-hardened, Croatia, against a team at their first tournament in a long time.
"We had a little spell just before half-time when we got the goal and looked exciting but Croatia are a top team and they showed that tonight."
Clarke declared a 2-0 defeat to the Czech Republic in the first group game to be a decisive result in an all-too-brief Scotland campaign.
But he has backed his young squad to learn important lessons from their first major international tournament.
He added: "I think we'll go away and learn from it for sure. Obviously starting on the back foot with losing the first game is something you'd need to address in the next one because that set us up for a difficult one.
"We left everything on the pitch at Wembley against England on Friday and couldn't quite get it tonight.
"I think through all the three games they've acquitted themselves well, they've tried their best, showed some good qualities. Obviously, as a coach I don't like to concede so many goals, it's something we have to work on a little bit, but we can improve.
"We've got young players in the squad, it's a relatively young group of players, and we want to improve together and hopefully we can do that."
Captain Andy Robertson echoed his manager's sentiments and urged his team-mates to turn this into a glorious era for Scotland by ensuring they also qualify for the World Cup in Qatar next year.
He said: "We're a squad that still has a lot of potential, still relatively new to this and not a lot of caps between us and it's important we build on this.
"It's important we don't take this as the high for this squad because we're a good team on our day and now we need to focus on September.
"I know it's a long way away, we need to go away on holiday and finally rest, but come September we need to try and qualify for another tournament because it can't go another 23 years.
"We want to be a team that qualifies for many tournaments and it become the norm that Scotland qualify.
"That's in our own hands, but we'll think about that another day."
As for the Croatia skipper, Modric, he preferred to revel in his nation sealing safe passage to the knockout stages in second place behind England rather than the wonderful curler he netted to set up the win.
The Real Madrid midfielder is now his country's oldest and youngest ever scorer at a European Championship, having done so at both 35 years and 286 days and 22 years 73 days old.
He told Euro2020.com: "This goal means a lot to me but our play means more, from the beginning until the end. I am happy that my goal helped, but it's most important that the team won.
"We are happy because we played a big match and qualified for the next round.
"We were not happy with performances in the first two matches and we knew we could be better. When we play like this, we are dangerous to everyone."
