Uefa have claimed they are unable to take any action over the racist chanting on the Paris Metro prior to the Champions League game between Paris Saint Germain and Chelsea on Tuesday night, because it happened away from the stadium.
A video has emerged of some Chelsea fans racially abusing a black man on a Paris train shortly before Jose Mourinho's team drew 1-1 at PSG.
The Chelsea supporters refused to let the man get 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".
Uefa have now claimed that, even though they condemn all forms of discrimination, the incident is outside their remit.
"UEFA condemns all forms of discrimination and we are appalled by the incident which took place on the Paris Metro on Tuesday" a statement read.
"However, as it occurred away from the stadium, it is outside UEFA's remit to act. It is a matter for the local authorities to investigate further and UEFA supports any action that is taken."
At the same time Fifa president Sepp Blatter has condemned the actions on his Twitter account.
