The Ivorian confirmed he heard offensive chanting during the Europa League clash at the Estadio Dragao with the young Italian also facing a poor reception as he was substituted
The Italian striker was substituted late in the game to a chorus of boos and whistles from the home support and the Ivory Coast star confirmed that he heard unpleasant chanting during the game.
English football has been rocked by racism scandals involving Luis Suarez and John Terry this season, and now looks set for another unfortunate saga.
When asked about the crowd's behaviour, Toure told SkySports: "That's why we all like the Premier League, because it never happens there.
"Maybe in foreign countries they don't expect black players. I think in future it will be OK, they will change their minds and the game will become more open.
"Football is football and the fans come to enjoy the game, and we don't want things like this to happen."
The powerful midfielder also reserved praise for Balotelli, who has a history of hot-headed behaviour, for maintaining his composure in the face of abuse.
Toure continued: "Mario is now able to control things like this and that is very important for the club."
