Troy Parrott is not a young man easily fazed.
He faced down the media after his full Republic of Ireland debut with absolute assurance.
The 17-year-old looks like a talent in control of his own destiny right now, and though his impressive display against New Zealand did not end with the goal those chilly 18,728 souls in attendance craved, there was more than enough on show here to keep the hype train fuelled.
Parrott is raw but loaded with ability, and he looked more than capable of living with the All Whites' rearguard on a physical level, often twirling away from burly defenders or holding off bodies with his back turned to goal.
He has just one senior appearance to his name at Spurs – a dour Caraboa Cup defeat to Colchester in September – but the Dubliner was one of the few to come out of that shock loss with any credit.
He has been marked as a player with every chance of making it under Mauricio Pochettino.
Still, the Belvedere Boys graduate wears the expectation lightly.
"I was just delighted to get out there, and walking out in the green jersey in my home town of Dublin was just the best feeling that I have felt," he said after Thursday night's 3-1 friendly win.
"I felt like I did well, I had a couple of chances, could have taken them maybe but I felt that I did well."
Whether he is kept with the seniors for Monday’s date with the Danes remains to be seen.
Lee O’Connor, another who stepped up with aplomb from the under-21s, will definitely return to Stephen Kenny’s camp for their qualifier against Sweden on Tuesday night.
Parrott’s place in the pecking order over the next few days is less clear.
"Of course, that is the dream for everybody," he said when asked if he could envisage sticking around for Denmark’s visit.
"It’s a massive game and we have taken the positive result tonight going into Monday.
"Maybe, if I go back down (to the under-21s), I will try to take stuff from this game."
Mick McCarthy is not a man known to lavish praise on players too easily; he takes the old-school approach of keeping the young bucks’ feet on the ground. But it’s safe to say he was happy.
"Just congratulations on the debut and stuff like that, but I haven’t had a chance to have a proper chat yet," Parrott revealed when pushed on what the boss’s appraisal was in the dressing-room.
"It was unbelievable just to be out there, running around and getting a kick of the ball in my international debut.
"I said during the week, it is about scoring goals and getting assists, and creating chances, so unluckily enough I didn’t get the goal tonight, but I am happy that I came away from the game with an assist (he teed up Sean Maguire for his thunderbolt).
"I’ve been satisfied with the strides that I have been making as I made my debut for Tottenham and now I have made my debut for Ireland.
"I’m just going to keep trying to do what I can do, train hard and learn off people, and then hopefully I can go far in the game."
He’s made a good start.
