Manchester City midfielder Yaya Toure was subjected to noises that sounded like monkey chanting as his side faced CSKA Moscow in Russia on Wednesday.
City have confirmed that they intend to submit an official complaint to UEFA over the alleged abuse, and a club official even spoke to the match delegate from the organisation after the match at the Arena Khimki with a written complaint to follow.
Toure spoke of his sadness over the matter at the end of the game after he appeared to point to referee Ovidiu Hategan to identify specific sections of the CSKA supporters who were allegedly abusing him.
The midfielder has been widely commended for his inspirational and dignified response to the incidents and in reporting what happened via social media and interviews.
The Ivory Coast international told Sky Sports: "It is quite disappointing when you're talking about people continuing to do that.
"It is unbelievable and very sad on my part.
"I think UEFA need to do something strong. It would be nice if we could stop that.
"Some of the songs today were quite stupid and I think UEFA has to do the work.
"Every time we say something it continues, something has to be done to stop it."
The papers were full of praise for the way that the City star reacted to the reported abuse and spoke with such 'strength' and 'class' after the match.
Toure Tweeted after the match: "Thank you for your support! Hate or racism cannot affect me when so many people are showing me love and support on a daily basis!
"I believe in football institutions, I know decision makers will take their responsibilties and show A RED CARD TO RACISM."

There was a great deal of support for Toure on social media with many fans keen to say how impressed they were with his conduct throughout.
Yaya Toure extremely dignified, mature & sensible talking about racist chants. Class act

Dignified response from Yaya Toure in the face of blatant racism from CSKA fans, calling it 'disappointing'! Disgusting is more appropriate! — Michael McCarthy (@mkmccarthy1989) October 23, 2013
The incident comes 18 months after Porto were fined £16,700 by UEFA after their fans racially abused Mario Balotelli during a Europa League clash against City in February 2012.
City also lodged an official complaint on that occasion, when monkey-chanting had been prolonged and widespread.
Controversially, City were later fined £24,740 for delaying the kick-off of the second half of that same game by one minute.
All eyes will now be on UEFA to see if they react strongly enough to this most recent episode.
