A video has emerged of Chelsea fans racially abusing a black man on a Paris train shortly before the Blues' Champions League game with Paris Saint-Germain.
The amateur footage shows rowdy Chelsea fans preventing the man from getting on the train at the Richelieu-Drouot station, while repeatedly chanting: "we're racist, we're racist, and that's the way we like it".
Paul Nolan, a British expat who captured the video on his iPhone and passed it on to the Guardian, told the news outlet: "The doors were open and I could see and hear that a lot of chanting was going on. It looked like it was quite aggressive so I just took out by phone to record it."
"He was obviously completely shocked when they pushed him off. I don't think he realised who they were. He then tried to get on again and got pushed off a second time.
"I was just completely appalled by it and so that's why I tried to catch some of it on my phone, although I was a bit self-conscious as it was getting quite aggressive and I overhead one of the Chelsea fans say something about stabbing someone. I think he was referring to a Paris Saint-Germain supporter who was on the platform."
A club spokesperson described the behaviour as "abhorrent" and said that it would support any criminal investigation.
Chelsea managed to hold the Ligue 1 Champions to a draw in the first leg of the last 16 Champions League tie.
