Rangers striker Jean Claude Darcheville has welcomed Uefa's pledge to launch an inquiry into alleged racist taunts by FK Zeta fans in the Champions League.

Darcheville and DaMarcus Beasley were both subjected to verbal abuse during the Ibrox side's 1-0 win in Tuesday's third qualifying round.
"When we're subjected to something like monkey noises, I feel that's not right," he told BBC Sport.
Spokesman William Gaillard said Uefa had a zero tolerance policy on racism.
He told BBC Five Live that Uefa decided to open an investigation "as there were many witnesses who reported the problems".
This is the 21st century and we are still having trouble with racism
He added: "We have to find out the hard facts and that will be done through the reports of the referee and the delegates.
"Also, if there were any other independent observers at the game, send us their reports and we always take those into account. We'll be thorough in our investigations."
A Uefa spokesman told BBC Sport on Thursday that both clubs would be notified of the report's findings within a week.
Darcheville said he believed European football's governing body was right to investigate the taunts.
"I find the racism abhorrent and people lower themselves through it, but it still continues even though I find it really low," said the striker.
Beasley, who hit the 81st-minute winner against Zeta, revealed he suffered similar abuse when playing for previous club PSV Eindhoven.
"This is the 21st century and we are still having trouble with it," he stated.
"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."
Uefa will also look into other incidents in which bottles were thrown from a stand containing home supporters and Rangers substitute Charlie Adam was struck by a lighter.
There were no reported incidents of Rangers supporters misbehaving during Tuesday's game.
They had been warned that any incidents of sectarian chanting could result in strong-handed action by Uefa against the club.
