Kick It Out have condemned the behaviour of alleged Chelsea fans singing vile chants about Liverpool’s Mohamed Salah.

A video of a small group of Chelsea fans in Prague branding Salah “a bomber” has gone viral on social media, with Kick It Out ready to speak to the club after describing the chant as “a disgrace”.

Chelsa security team were studying the video to identify the individuals and prevent them from entering Slavia Prague's Eden Arena to watch the game. It later emerged that three of the six alleged Chelsea fans were stopped from entering.

Salah, a former Chelsea player, is of Muslim faith and the sick song is another damaging blow to the club’s reputation, following a number of other incidents this season.

Kick It Out, the anti-discrimination group, issued a statement on social media with the video linked to the message. The video appears to have been taken in the Czech Republic, before Chelsea’s Europa League quarter-final first leg against Slavia Prague on Thursday night.

"It's not on the terraces but it is still a disgrace. We do not want fans like that anywhere near our game,” it read.

"We will be liaising with Chelsea Football Club to ensure those involved are identified and punished swiftly and effectively.”

Chelsea fans on social media have also hit out at the group of fans, with the club declining to comment "on the basis it has not been established yet they are Chelsea fans".

Earlier this season a section of Chelsea’s supporters were alleged to have chanted racist songs about Spurs fans in the Europa League game against MOL Vidi. Uefa investigated before deciding “to close the proceedings”.

Some Chelsea fans were also alleged to have abused Manchester City and England winger Raheem Sterling during a Premier League match in December. Four fans were suspended by the club.

After those incidents Chelsea chairman Bruce Buck admitted the club “have a problem” with racism but pledged they “would not rest”.

In an open letter to fans he wrote: "These actions are unacceptable and unwelcome both in our club and in football.

"A deeply unpleasant but vocal minority which refuses to join us in the 21st century has shamed the great majority of our decent, well-behaved fans.

"We will continue to take the strongest possible action against anybody found to have been using discriminatory words or gestures. But we must all come together to stamp out these ugly scenes."

Chelsea travel to Anfield on Sunday for a crucial match in the Premier League title race which will come on the eve of the 30th anniversary of the Hillsborough disaster.
