UEFA has opened disciplinary proceedings against Atalanta following alleged monkey chants from the club's fans during last week's Europa League clash with Borussia Dortmund .
Dortmund's Belgium striker Michy Batshuayi, on loan from Chelsea , claimed after the second leg of the last-32 tie in Italy that he was the subject of alleged racist chants.
European football's governing body confirmed on Monday afternoon that Atalanta faced charges of "racist behaviour (monkey chants)", the setting-off of fireworks, throwing of objects and blocked stairways, while Dortmund were charged with the setting-off of fireworks and throwing of objects.
UEFA's control, ethics and disciplinary body will deal with the case on March 22.
Batshuayi played the entire 90 minutes of last Thursday's second leg as substitute Marcel Schmelzer's 82nd-minute equaliser salvaged a 1-1 draw on the night which sent Dortmund into the last 16 with a 4-3 aggregate win.
