United swooped for McGinty at the end of last season from Charlton Athletic and the youngster told fai.ie: "I was delighted to win an Under-17 cap last season while still an Under-16 player and I'd like to use that experience to benefit the team.
"This is my third season with this squad and it's changed quite a lot over since we started out at Under-15s. We came up against some of the best teams in Europe last season - Portugal, Spain and France - and, though the results weren't great, we learned a lot from playing those matches.
"The difference this season is that most of the lads are in full-time training with their clubs. I think fitness will be vital when it comes to playing our European qualifiers later this month."
