NB: what you see above is just an impression of the clip: since The Guardian has chosen to block access via YouTube to footage it should want the world to see, I will use the BBC link suggested by Phil in the comment below. See it at http://www.bbc.co.uk/news/uk-31515624
The bad news is that this happened in 2015. Long after we fondly supposed such low-life primitives had found other outlets for their vile prejudice, a group of English “supporters” are caught on film preventing a black man from boarding a Metro train in Paris before the Chelsea game at PSG. They chant “we’re racist, we’re racist and that’s the way we like it”.
