Picture: A racist Chelsea fan is snapped making a monkey gesture towards Manchester United’s Danny Welbeck

Pessimists were always fearful that there was going to be at least one idiot at Stamford Bridge on Wednesday night… and so it proved.

A Chelsea fan has managed to help tarnish the entire west London football club by being pictured making a monkey gesture towards Danny Welbeck during the Blues’ epic 5-4 win over Manchester United in the Capital One Cup.

In the wake of Chelsea’s still-to-be-proven claims that referee Mark Clattenburg called John Obi Mikel a ‘monkey’ during last Sunday’s Premier League match with the Red Devils, this picture could scarcely prove more damning for Roberto Di Matteo’s men.

We wait to see how Chelsea will react to this picture which is quickly being spread around social media sites.
