However, tournament officials, as well as the UEFA organisers, have made it clear there is no issue of refereeing standards being in question.
The controversy over the referee comes as Rehhagel rejected suggestions he could be in line for the Germany manager's job after Ottmar Hitzfeld turned the position down yesterday.
Rehhagel said he would honour his contract with Greece, which runs until 2006, and would not be vying for the Germany vacancy. He said: "My job is to deal with my boys and the team and prepare them for the final. That's what my role is and nothing else."
