Ronan Curtis toasted his maiden Republic of Ireland international cap and declared: It's a dream come true.
He replaced Callum O'Dowda at half-time at the Aviva Stadium and looked lively as he made the step up to the senior international stage.
The latest milestone in Curtis' career comes following his impressive start to life at Fratton Park.
Since arriving at Pompey from League of Ireland Derry City in June, he has firmly established himself as a fans' favourite.
His 17 appearances to date have seen him score score six goals and assist in another seven as the Blues sit top of League One.
Curtis admitted it has been a unbelievable six months, which had been capped off with the ‘honour’ of making his debut for the Republic of Ireland.
Speaking to Highland Radio, he said: 'Words can't describe how over the moon I am right now.
'Six months ago I was at Derry just going into Portsmouth and it's just a dream come true really, making my debut.
'It's a huge honour.
'When I was a little kid I always wanted to grow up and play for my country, and I've become that.
'I've made my debut and I'm over the moon.'
Despite his confident demeanour on the pitch, Curtis admitted even he has been surprised by the upward trajectory of his career since swapping Derry's Brandywell Stadium for life at PO4.
The 22-year-old confessed he wasn't expecting to make the instant impact he had made for Kenny Jackett's side.
Curtis set up Jamal Lowe for the Blues' only goal in the 1-0 win against Luton.
He then bagged a double in Pompey's 2-1 victory over Blackpool a week later.
'Where do I start', joked Curtis.
'I went to Portsmouth and didn't think I would play as much.
'When the gaffer gave me the nod for the very first game of the season, playing in front of 22,000 a week, compared to 4,000 at Derry, it's a crazy feeling.
'I made my debut, set up the goal in the 1-0 win, got the assist, and my confidence was sky high going into the next game.
'I ended up scoring two.
'Then I kicked on from there, confidence was flying, went away with the Republic of Ireland under-21s and scored against Kosovo.
'I got a yellow card and was suspended for the Germany game, and then Martin O'Neill gave me the chance to come up and train with the boys, and I just kicked on from there really.
'Now here I am making my debut.'
