UEFA have opened disciplinary proceedings against Porto for 'improper conduct' of supporters during last week's game with Manchester City.
Case launched over reports of racist chanting at Estadio Dragao
UEFA have opened disciplinary proceedings against Porto for "improper conduct" of supporters during the Europa League match against Manchester City last week.
City lodged an official complaint after Mario Balotelli and Yaya Toure allegedly suffered racial abuse from the crowd during City's 2-1 win last Thursday.
Balotelli complained about being subjected to abuse first, with midfielder Toure backing up his claim.
Porto claimed they were surprised by the accusations from City saying some of the chants could be mistaken for something else
UEFA announced in a statement: "Following a complaint lodged by Manchester City FC, UEFA has today opened disciplinary proceedings against FC Porto for the improper conduct of supporters (article 11 bis of the UEFA disciplinary degulations) during their UEFA Europa League round of 32 first-leg match against Manchester City FC last week.
"The UEFA control and disciplinary body will deal with the case on 29 March."
