Chelsea look to refocus

London - Chelsea will aim to refocus on their Premier League title challenge on Saturday after the club was shamed by the racist behaviour of a handful of their supporters in Paris.

A French-Mauritanian commuter was blocked from boarding a train by a group of Chelsea fans travelling to the Parc des Princes for the 1-1 Champions League last 16 first leg against Paris St Germain on Tuesday.

A chant of "We're racist and that's the way we like it" from the Chelsea fans was clearly audible on a video of the incident at the Richelieu-Drouot Metro station.
