Uefa have confirmed they are investigating allegations of racist abuse directed at Manchester United players in their UEFA Champions League clash with Benfica.
During the game at Estadio da Luz, which United won 1-0, Patrice Evra, Louis Saha, Kieran Richardson and Wes Brown were all reportedly the target of abuse of a racist nature.
Whilst Benfica have denied the accusations, The Red Devils made a written complaint to Europe's governing body after returning from Portugal.
As a result Uefa have now launched a probe into the alleged behaviour of the Benfica fans.
"Uefa is investigating a written complaint made by Manchester United FC about alleged racist conduct by spectators at the UEFA Champions League Group F match against SL Benfica in Lisbon on 26 September," read a statement on Uefa's website.
"The English club has submitted the complaint, following allegations by United players that they were subject to abuse of a racist nature at the game in Portugal, with United won 1-0."
If found guilty, the minimum punishment Benfica can expect to receive is a fine of £14,000, whilst Uefa also have the power to impose a points deduction or exclusion from the competition.
