Greece stars insist they were promised one million euros a man for winning the Portugal finals, but Greece international striker Vassilis Tsiartis of FC Cologne claims they have only received 750,000 euros.

"A year ago they were calling us heroes," Tsiartis told Bild am Sonntag. "But now it is clear what they think of us. We were promised a certain amount but that promise has not been kept."

Greek sports minister Giorgios Orfanos countered that claim and said talk of a one million euro win bonus was wide of the mark.

Greece were the surprise package in Euro 2004 defeating hosts Portugal 1-0 in the final courtesy of an Angelos Charisteas goal.

On Thursday Otto Rehhagel's side face world cup holders Brazil in Leipzig in their opening match of the Confederations Cup.
