Vlahovic's goal in injury time angered the Bologna fans.
Among them Patrick Zaki who, immediately after the match against Juventus on Saturday wrote a tweet in which he commented on the match.
Since then, there has been a continuous stream of comments on his bulletin board, especially from Juventus fans, who contest his words, in some cases even with insults and threats, bringing into question his legal case in Egypt, where he risks a conviction for crimes of opinion.
"If I can't say my opinion on football without being attacked - he says - I'm not sure how I should recover my voice in more important matters."
The affair was denounced by Amnesty International.
"'You are talking too much' - says the spokesman Riccardo Noury - is one of the comments, including insults and other threats, published in the last hours against a person who, for 22 months, lost his speech in an Egyptian prison and is still on trial: Patrick Zaki. All for a fan tweet. You're in bad shape. "
Patrick Zaki himself returned to the story with a long post accompanied by a photo of him with the Bologna shirt.
"I have been faced with dozens of insults and aggressions - says the Egyptian student - up to hatred. I don't mind having regular heated discussions with fans of different teams, I love football and I appreciate this kind of fun. However, when I found that people were hoping that I would go back to prison and be silenced, it really struck me how hate speech can be triggered so easily.
I honestly don't understand how this escalation was so rapid and why after two years of silence , I am attacked by the same people who once supported me, just because I said my opinion on the game "
