The Greek kid impressed against Philadelphia Union last week.
"I remember these players from when I was younger," he laughs. "The likes of Phil, Tim Cahill, Mikel Arteta ... I would collect sticker albums with them in! So it is a dream for me to be here," he told the Liverpool Daily Post.
"The first team players help me so much. They give me strength and confidence and the belief that one day I can be one of them.
"I thought the stadium in Philadelphia was very good, there was a great atmosphere throughout the match and it was a good game to play in.
"The people, the fans, were fantastic and it was great to see that these people came to watch us. We have to give many thanks to them.
"Forty-five minutes is the most I have had for the first-team since I have been here. I was probably, along with all the other players, a little tired afterwards!
"But I am not worried because we are training hard for a reason. We train hard because it benefits us when we come to play matches and because it will help us to be ready at the start of the season next month."
