The Everton midfielder, 19, made his debut as a second-half substitute in September's World Cup qualifier against Moldova having been fast-tracked from the U21s, for whom he has made just five appearances.
He has been a key performer in Everton's impressive start to the season and although the prospect of the World Cup looms large next summer, he insists performing well for his club remains his priority.
"It's every youngster's dream to play in the World Cup," he told evertontv.
"But I'm not really thinking about it at the moment - hopefully if I play well for Everton then I will push into that team and get to Brazil.
"It was a nice surprise to be selected in September's squad. It just shows that hard work pays off.
"The first two days I'd say there were a lot of nerves but then it settled because it felt like I was meant to be there.
"It's helpful being around different players that I'm not used to - being around big-name players - it's good just talking to them and seeing the way they approach games. It bodes well for future games for me.
"It was unfortunate I just missed out on a goal but it's always good playing for your country.
"To come on for the seniors was a great feeling and a good moment for my family as well."
