Rangers match-winner DaMarcus Beasley insists UEFA and FIFA must take a hard line stance against racism after he was targeted by FK Zeta fans making monkey noises during last night's Champions League tie.
The UEFA match delegate included the actions of the home supporters in his report and the end of Zeta's European campaign could be followed by heavy punishment.
American Beasley had experienced similar in the past, and he fears the message that racism is unacceptable is just not getting through to supporters in some countries.
Beasley hit the late winner as Rangers prevailed 1-0 on the night and 3-0 on aggregate.
Afterwards, the former PSV Eindhoven winger promised to discuss with Rangers whether the club should make an official complaint.
He said: 'That's something FIFA and UEFA must fight with, and solve.
'This is the 21st century, and we are still having trouble with it.
'That's not normal, not just for us, black players, that's not normal for all other normal people.
'I've faced that kind of situation throughout my whole career in Europe, not so much during my playing days in England, but even in Holland I've had similar problems.
'There, at PSV, the club's management held meetings with me, trying to solve that together, but, things happened, especially at some European matches.'
He added: 'It sickens me to hear these chants but when you are on the pitch you have to try to blank it out. It degrades the game for everyone.
'I will discuss the situation with Rangers because I feel strongly about it and we will decide if we should file a complaint.'
Beasley fears the worst might still be to come, with Red Star Belgrade potential opponents in the final round of qualifying for the tournament proper.
The Serbian side lead Levadia Tallinn 1-0 after the first leg and face a tricky test in Estonia tonight.
Beasley recalled a Champions League qualifier he played for PSV against Red Star in August 2004, when he also came in for abuse.
He said: 'I remember playing against Red Star Belgrade, and I mention them as they could be our next opponents in the Champions League, and I still remember some racist chants at that away match.
'As a club (PSV), we did our best to point our finger at that problem, we warned UEFA on that, but I can't remember if there was any serious reaction after it.
'Maybe I'm wrong, but despite that, I'm sure that UEFA, and FIFA, are doing their best, too, to kick racism out of football, as it is necessary for us all to play in healthy sport.'
UEFA will also consider incidents in which bottles were thrown from a stand containing home supporters when Zeta were denied a penalty in the second half, and when substitute Charlie Adam was struck by a lighter.
There were no reported incidents of Rangers supporters misbehaving during the match. They had been warned that any incidents of sectarian chanting could result in strong-handed UEFA action against the club.
Rangers boss Walter Smith admitted he had not heard the abuse, having been absorbed in the game.
He said on the club's website: 'If it did happen I wasn't aware of it but the players coped well with the atmosphere.'
