Olivier Giroud insists the fans who inflicted further damage on Chelsea’s reputation in Prague “don’t belong to the club”, as manager Maurizio Sarri pleaded with supporters to observe the minute’s silence at Liverpool this weekend.

Giroud, the Chelsea forward, has condemned the fans who chanted vile songs about Mohamed Salah before the Europa League quarter-final first leg with Slavia Prague on Thursday.

Three fans were prevented from entering Slavia’s Eden Arena by Chelsea security, after footage emerged on social media of the small group singing a racist song about Salah, which has left Stamford Bridge officials furious.

Chelsea face Liverpool at Anfield on Sunday in a crucial Premier League game, with the club warning that any further disturbances will lead to the “strongest possible action”.

In the FA Cup semi-final between Chelsea and Tottenham Hotspur in 2012, a minute’s silence to pay respect to the 96 Liverpool fans who lost their lives in the Hillsborough disaster was cut short after a section of Chelsea fans jeered and booed.

Sunday’s game at Anfield will be emotionally charged ahead of the 30th anniversary of the tragedy, and Giroud insists there cannot be a repeat.
