Chelsea launch investigation into racist gesture by fan towards Manchester United player Danny Welbeck

Chelsea have launched an investigation after a supporter was photographed making an apparent racist gesture towards a Manchester United player, believed to be striker Danny Welbeck.

The picture, published in more than one national newspaper, seems to show a fan making a 'monkey' gesture during last night's Capital One Cup clash between the two clubs at Stamford Bridge.

Police are also aware of the photograph but have not yet received a formal allegation on which to open a criminal investigation.

A statement from the club read: "Chelsea Football Club can confirm we are investigating an incident involving a member of the crowd at last night's game against Manchester United.

"The club will be examining all available footage and asks anyone who can identify the individual to contact the club.
