The game, which took place in Paris Tuesday and ended 1-1, has been overshadowed by the release of a video showing what appears to be a group of Chelsea fans preventing a black man from entering a metro train whilst chanting “We’re racist, we’re racist and that’s the way we like it”.

The man in the video, which was widely shared on social media, was later identified as Souleymane S., a 33 year old Parisian on his way home from work.

The incident made headlines worldwide, drawing condemnation from Chelsea coach Jose Mourinho, the club’s secretive Russian owner Roman Abramovich and even French President Francois Hollande.

“It’s clear that unfortunately there is still a minority who think it is acceptable to behave in such an abhorrent manner,” Superintendent Gill Murray said.

“The men shouted as they walked through the station having alighted from the train a short time.
