Basically, the boos against Juventus' black players made him feel bad, and says that whoever's doing it should stop because they're damaging Lazio's international reputation and closing the Curva. He then says that a lot of people identify all Lazio fans as racist. He says they tease him in France because he's a black Lazio fan, and it makes him feel bad. He explains that Lazio fans aren't racist, but when he hears the boos like he did yesterday, there's nothing he can say. Lazio are a famous club and deserve to be praised, and not just talked about for these racist episodes. Sorry for the ouburst, but I need to speak my mind because I spent six intense seasons with Lazio and I loved it and I want other people of any colour whether it be black, yellow, white or green to understand the meaning of Lazialita and how special it is to cheer for or play for this team.
EDIT- Sorry for saying the same thing. It took me a long time to write this out.
