Portugal's football federation is unhappy about the appointment of Scottish referee Hugh Dallas for their World Cup match against Poland.
Dallas is being tipped by some as the main rival to Italy's Pierluigi Collina for the final itself.
But the Portuguese have not forgiven the Scot for his role as the fourth official during the semi-final of Euro 2000 in Paris.
France were awarded a late penalty after Slovakian assistant referee Igor Sremka spotted Abel Xavier's handball in the box.
Sremka has been chosen by Fifa to again run the line, this time with Dallas officiating on the field of play, when Portugal face Poland in Group D on 10 June.
Portuguese FF vice-president Antonio Boronha said: "We have made our feelings known.
"We find it strange that Hugh Dallas and assistant Igor Sramka will referee the match.
"We know the rules and we understand who nominates the referees and we respect that.
"But we feel it is odd. Those same officials participated in the portugal-France semi-final, which we lost 2-1 amid regretable scenes, after which there were severe bans for Portugal players."
Xavier was given a nine-month Uefa ban for "violently grabbing the arm of the assistant referee".
Nuno Gomes and Paulo Bento received lengthy bans after being reported by Dallas for dissent and aggressive behaviour.
Meanwhile, Fife have insisted that there has been no formal complaint lodged about the officials for the Portugal-Poland match and that it was extremely unlikely that they would change any such appointments.
