The 16-year-old, who plays for Olympiakos, has been linked with a move to Manchester United in the January transfer window.
“It’s an honour for me to hear that Manchester United show interest,” Papadopoulos told the Greek media.
“Personally, I don’t know anything official yet. I just hear the rumours. I am an Olympiakos player and I am focused on Olympiakos right now.
“I will keep working and, if anything is going to happen in the future, I will be very proud if it’s going to be for Manchester United.”
He added: “The fact that many European clubs have watched me in the last months doesn’t make me nervous. It’s a pleasure.
“Is it going to be hard to leave Greece at the age of 16? Not at all.
“If a player really wants to play football out of his country, and the situation at his new club is good, I don’t see a reason not to try.”
