Coventry City Under-18s striker George Thomas believes his experiences with the Wales Under-19s side has only helped him progress as a player.
Thomas returned to City training today after his three-game spell with the Welsh Under-19 side in Portugal with City team-mate Cian Harries.
Wales failed to qualify for the UEFA Elite Round despite an impressive performance against Portugal and a win over a highly-tipped Albania side.
The 17-year old has lauded the experience he had with Wales and has also praised City team-mate Harries for his progression this season.
Thomas said: "It hasn't been too different stepping up from the Under-17s because a lot of us from the group have stepped up to the Under-19s. It is a great environment.
"Cian has had a really good season and his head has really come on which is great. He's a great player and when we go away together, he is also someone you can come back to and talk about things with.
"That can be really important when you're away to have someone you know. I've really enjoyed it recently and I think it has definitely helped me progress.
"The same standards are expected with Wales as here at Coventry. The only difference being is they're a low press side whilst we press the ball quite here at Coventry."
Thomas played 78 minutes in the 2-1 defeat to home side Portugal and scored for Wales in the 2-1 win over Albania on Monday.
Despite admitting he was disappointed not to qualify for the latter stages of the UEFA Under-19 Championships, Thomas says there was a lot of promise in the performances.
He added: "It is really good for the Under-17s next year as it is a young group but we're all disappointed not to qualify of course.
"I think we've got to concentrate on the positives in our performances. When we played Portugal, I think we should have got something out of the game and they're top quality opposition.
"I was happy to get the minutes I did during that game and the Albania game. I was happy with the goal as it was a nice reverse pass and I finished through the keepers legs.
"They were a really good side and they didn't take any prisoners with three red cards in the game. It was a tough match and it was great to get the win."
Now back at the Sky Blues, Thomas has his sights fully on the FA Youth Cup game against Rochdale next Wednesday and has praised coach Jason Farndon.
He added: "Jason has been great with the players this year and there is a really good environment in the camp.
"We're doing really well in the league but next up is the FA Youth Cup and we're determined to push on and make a real impact in the competition."
