Shane Duffy says he's looking forward to working with the new batch of Irish players on a training camp in Turkey next week, and he's confident the fruits will be seen in four years' time.
While senior players like Stephen Ward, Darren Randolph and Richard Keogh have been excused from international duty for the Turkish trip and Friday's friendly in Antalya, but Duffy will be on board Monday's flight.
"I will always go with Ireland if I am asked, I look forward to the games," he says.
"It's difficult in that it's a friendly, we'd much prefer to be preparing for a World Cup but it's great to get another cap, if I am picked, and see the lads again. It's been a while since we met up and the squad is different.
"I was speaking to Seamus Coleman about it on Saturday, the squad is different now, things move on with time, the lads who have retired did really well but it's the time for the younger players, the likes of Declan Rice, Darragh [Lenihan] and Derrick [Williams] at Blackburn, Seanie Maguire is flying.
"We have good players and hopefully we have a squad we can build for the next two to four years and have something good at the end of it."
A key member of the squad heading towards Euro 2020, Duffy admits that he's still learning at international level, taking lessons from lows like the 5-1 loss to Denmark.
"You learn all the time, I have had bad experiences and I have learned from them," Duffy says, recalling the times when Antone Griezmann got the btter of him (and won a penalty) at Euro 2016 as well as Christian Eriksen's Dublin display.
"You know you will have lows in your career to make the good moments better. Griezmann, for example, I will always think of that one and think 'don't get yourself in that situation where you have to make that foul'.
"The same with Erriksen, you can't give him space, but I am adapting. If a player is better than you, sometimes you just can't do anything about it.
"I think Chris Hughton was more cut up than me over the Denmark game. He spoke to me after it, he was disappointed that we lost the lead and lost the game, we were one game away from the World Cup, we were at home, where we had been solid, not conceding many goals and then we go and have the worst night."
