Rangers winger DaMarcus Beasley and striker Jean-Claude Darcheville were subjected to taunts by the home fans during the second leg of the second qualifying round tie in Podgorica.

USA international Beasley scored the only goal of the game in the 81st minute to earn the Gers a 3-0 aggregate victory.

UEFA director of communications William Gaillard said: "We haven't yet received the report from our delegate but we have enough circumstantial evidence to begin our investigation.

"Our policy is zero tolerance against racism.

"The control and disciplinary body is an independent commission and it is for them to decide, but it is one of our priorities to eradicate this, it is a major concern."

Gaillard did not have an official timeframe for the investigation but added: "It will be quick, in the next couple of weeks probably."

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.

e 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 www.rangers.co.uk: "If it did happen I wasn't aware of it but the players coped well with the atmosphere."
