Chelsea has made a complaint to UEFA about racist abuse being aimed at one of its players by Dynamo Kiev fans during a Europa League match. The English club says the abuse took place near the end of its 5-0 win in the last 16 on Thursday and that the matter was reported to the referee at the final whistle. Chelsea chairman Bruce Buck and club secretary David Barnard then spoke to UEFA's match delegate. Chelsea says "we wholeheartedly condemn such abhorrent behavior" and "expect UEFA to conduct a fulsome investigation." The club didn't say which player was the target of the racist abuse. Britain's Press Association says it was winger Callum Hudson-Odoi, who is black.
