Craig Davies says it is an honour to join up with the senior squad after a hat-trick for Wales Under-21.
The Verona striker, 20, got a first half treble against Estonia before joining the senior squad for Saturday's friendly with Trinidad & Tobago.
With Ryan Giggs and Craig Bellamy out and Rob Earnshaw carrying an injury, he could start the game in Graz, Austria.
"I've had a few substitute appearances and they were very proud moments for me and my family," said Davies.
"[Wales manager] John Toshack has just told me to keep doing the simple things, keep my head right and be focused on football.
"That's what I have been trying to do. I have had a couple of weeks with the Under-21s and a week with the seniors and that has been very good for me, certainly for the future."
I am now based back in the UK looking for a loan move for next season
Davies - substituted early against Estonia at Toshack's request - is seen by the manager as one of the few viable target-man options up front for Wales following the retirement of John Hartson from the international game.
He could feature up front against T&T alongside highly rated Bristol City teenager David Cotterill.
But Davies is currently searching for a British club after a troubled spell in Italy following his move from Oxford in January.
"It has been a difficult time for me of late and I am now based back in the UK looking for a loan move for next season," he said.
"I haven't actually been released by Verona, they have another three years on my contract and they haven't given up on me.
"But I have found it very hard to settle in Italy. I have been out there on my own, I don't speak the language and very few players my age go out there.
"I want to sort something out in the next couple of weeks, and scoring a hat-trick for the Under-21s hopefully has helped.
"Verona want me to come back and have a year on loan somewhere and then they will look at the situation again when I have a bit more experience."
