There have been calls to kick Slavia Prague out of the Europa League after a number of the Czech club's fans held up a vile banner calling Rangers midfielder Glen Kamara a 'n*****'.
Rangers were beaten 2-0 in their European clash with Slavia, losing 3-1 on aggregate, but the game was overshadowed by racism allegations that Kamara was called a a 'f***ing monkey' by Ondrej Kudela, which result in a bust-up on the pitch.
Kudela covered his mouth with his hand in an apparent bid to avoid the scrutiny of TV cameras, with Kamara later telling Steven Gerrard he was the victim of a racist comment.
Europe’s governing body are investigating the incident, while the Czech club claim in turn to have filed a criminal complaint against the Rangers midfielder for an alleged assault on Kudela after the game.
However, tensions have since escalated after the saga has taken another disgusting turn when 11 of the Czech club's supporters posed with a long banner that reads 'Kamara – just a n*****' while holding flares to light it up.
Another image posted on the same Instagram account shows the group holding another banner that read: 'Slavia Praha against all #TeamKudela.'
The banner, which was posted to social media on Friday night, was condemned by the Slavia Prague chairman, Jaroslav Tvrdik, who labelled it as 'disgusting' and 'pathetic'.
Though Slavia have stood by Kudela, who denies using racist language, the club say they will be taking the image to police.
The despicable banner has led to calls for stronger action to be taken against the Czech side – who are now in the quarter-finals.
Rangers legend Kris Boyd insists UEFA need to take the strongest possible action and set the precedent that racism will not be tolerate.
Boyd has demanded that Slavia must be kicked out of the competition and allow Arsenal to be given a bye into the semis.
He told Sky Sports: 'We need to take the strongest stance possible.
'For me that would be to kick Slavia Prague out of the competition. I'm not saying that with a Rangers head on or anything and get Rangers back in. The best team won.
'Kick them out and give Arsenal a bye into the semi-finals because it's not right.
'If it's swept under the carpet, it doesn't get dealt with. I think it was Kamara that said, "you give it the green light to continue". This racism in football is a disgrace. It's an absolute disgrace.
'UEFA have an opportunity to do something about it here.'
Boyd went on to claim that no fine would be enough to punish racist offenders and that the strongest punishment must be taken.
He added: 'How can we go about this and how can we ask society to change and do things if we've got a professional football player, on one of the biggest stages in football, actually racially abusing another professional player?
'It's not on. As I said, you can fine these clubs and you can fine them as much as you want – it is irrelevant and a stronger stance needs to be taken on this now.'
One fan wrote: 'Racist behaviour on the pitch and racist fans off the pitch. UEFA ban them now. This behaviour is disgusting. Watching Goldson interview is hard to watch. He looks exhausted the poor guy, because no one is listening about racism.'
Another Twitter user implored others to get the 'BanSlavia' hashtag trending while many showed their support to Kamara following the picture of the banner.
Following Boyd's comments, the hashtag 'BanSlavia' was started with fans agreeing that the Czech club should be punished for the banner.
