Midfielder Karagounis has struggled to break into the Inter Milan team since moving from Panathinaikos in 2003.
Club: Inter Milan
Debut: 18/8/99 v El Salvador
Behind Uruguayan star Alvaro Recoba in the pecking order, he has endured a frustrating time on the sidelines.
Karagounis attracted interest from several Serie A clubs after shining for Panathinaikos in the Champions League.
He remains one of Greek football brightest talents, but his Euro 2004 build-up was blighted after a sending off against Portugal in late 2003.
Karagounis came to prominence as captain of the Greek squad which nearly won the 1998 Uefa Under-21 Championship.
And his competitive style of play often brings favourable comparisons with Greece legend Mimis Domazos.
Did you know? Karagounis scored from a direct free-kick for Panathinaikos against Manchester United in a Champions League match in 2000.
