Born in Australia to Greek parents, he failed to make the Olyroos squad for the Beijing Olympics so decided to fall back on the Greek squad and play with the U19s. He has previously represented Australia at U23 and U17 level.
Reds manager Rafael Benitez plans to use his full list in upcoming pre-season trips to Switzerland, Spain, Norway and the UK, but the fact that some of his young charges will be playing at the Euros could complicate things.
Benitez was upbeat when quizzed on the situation on the club's official website.
He said, "Clearly some of the young players will be involved in some of our games during pre-season and this is an opportunity for them to show what they can do, although some of them are so good they will play some games with their national teams.
"But we have a lot of confidence in them so if they can be with the first-team players and work with coaching staff I am sure it will be good for them.
"It is important that they develop their experience at this stage of their careers and afterwards we will see but it is clear that they have a chance."
