Football: Arsenal to investigate Koulibaly 'racial' video
Arsenal are investigating a video circulating on social media which shows one of their supporters directing a racist insult at Napoli player Kalidou Koulibaly.
The video surfaced after last night's Europa League quarter-final first-leg clash with Napoli at the Emirates Stadium, which the gunners won 2-0.
Arsenal has since released a statement saying that they operate zero tolerance approach to racism.
"We operate a zero tolerance approach, and anyone behaving like this is not welcome at Arsenal and will be banned from matches.
"We have an extremely diverse community of fans who are all part of the Arsenal family and such incidents are rare at Emirates Stadium. We encourage supporters to report any incidents as they happen to stewards or via our matchday alert service."
"We utterly condemn the use of any racist language and have launched an investigation to identify the culprit.
