Should new Socceroo Apostolos Giannou play only his third international game this Saturday, he'll hold the extraordinary distinction of having played for and against Greece at senior level. 
But Giannou's appearance for Greece against Turkey last   Novembershould never have happened.
The Hellenic Football Federation have been fined $6000 by FIFA's Disciplinary Committee for fielding the striker without registering his passport, leaving the match to be declared a 3-0 forfeit.
Players are not usually permitted to change nationalities after featuring at senior level, unless they've only played in friendlies - a loophole Football Federation Australia exploited to get the 26-year-old to switch to the Socceroos.
Giannou made his international debut for the nation where he was raised against Tajikistan in Adelaide - a qualifying game that tied him to Australia once and for all.
The former Oakleigh Cannons junior will get the chance to play against Greece twice, first in Sydney at ANZ Stadium on Saturday and then in Melbourne at Etihad Stadium three days later. ''I don't want to focus on being Greek and changing to Australia. My mentality is to play as good as possible and help the team as much as I can. I am just trying to block out the other stuff and focus on Socceroos,'' he said on Thursday.
''It's exciting and a bit strange because I was with most of these boys in   November, playing together, so it's weird situation.''
Giannou said he'd spoken to many of the Greek players and said none of them resented his decision to switch to Australia.
''I am excited to see them again because I have got very good friends in the national team that I played with in Greece,'' he said.
