And during the last campaign the Serie A club banned several supporters after they chanted discriminatory remarks about Balotelli during a cup match against Napoli.
"I think a new season is a chance to show new behaviour, and to show also at a European level that the Italian supporters, or more particularly those of Juve, have understood the messages and the sanctions that were handed out," said Juventus general manager Jean-Claude Blanc.
"Supporting your team is to support your team, and not to make remarks of a racist nature toward other players. We will be extremely demanding and intransigent about this."
Brian Marwood, Manchester City's head of football administration, said: "Mario, like all of our players, I'm sure, will be relishing the opportunity.
"He's a young man with an incredibly bright future ahead of him and we will give him every support and help that he needs.
"We will leave it to the authorities to deal with anything that happens but we are not anticipating any issue."
Liverpool skipper Steven Gerrard admitted that the Europa League is not his club's top priority - but is confident the Reds will progress from the group stage.
"It's a strong group and I'm certainly looking forward to the games," said Gerrard.
"I'm confident we can get out of the group but it will be tough. I don't think the Europa League is the priority. Everybody knows that our league position, where we finish at the end of this year, is the priority.
"But it's another trophy, it's a big cup. We haven't won a trophy for four years now so it's important we put a good show on in all the cup competitions and try to reward the fans with a final."
Group J also looks extremely competitive, with Sevilla, Paris Saint Germain, Borussia Dortmund and Karpaty Lviv all competing for the top two places.
The group stage begins on 16 September and when it concludes three months later the top two teams from each group will go through to the final 32 - where they will be joined by the eight third-placed finishers in the Champions League group stage
