Michy Batshuayi has alleged that he was subjected to racist chants during Borussia Dortmund's last 32 second leg clash at Atalanta, and the forward took to social media to hit back at the fans involved.
But that didn't stop the 24-year-old from leaving with a bad taste in his mouth after fans of the Serie A side allegedly made monkey noises toward the Belgian throughout the match.
Batshuayi hit back on Twitter after the match.
The actions from the Atalanta fans are nothing new.
The club faced sanctions in January after the fans were found to have racially abused Napoli's Kalidou Koulibaly.
In that instance, the Serie A side were forced to play a match behind closed doors.
