"It's hard to judge this," he suggested.
"Anyways, I'm very sorry for a guy like Balotelli, but if he leaves I am convinced Calcio will still go on without him."
The Citizens will reportedly dish out €30-35 million for the Italy Under-21 goal-scorer and Simoni believes that is a fair estimation as he explains the temperamental star still has to prove himself.
"It's the right price for me. Now we will have to see whether it would be a positive or negative deal for City. If he plays to his potential, City have a deal, if he doesn't play as he is capable then City have spent a lot of money," rationalised the 71-year-old.
"Certainly the boy has unique qualities, but sometimes can go looking for trouble. Personally, I feel that players like Balotelli are uncertain. Think about [Diego] Forlan and [Dirk] Kuyt who are true professionals.
"Maybe they are not quite like Balotelli, but with some players you always prefer never to take chances."
Nonetheless, Simoni is confident that Serie A has not seen the end of 'Super Mario' should he move to Eastlands, whether it be for the national team, in European competition, or maybe one day a return to the top flight in the peninsula.
"At the start the departure of Balotelli seems like a bad loss, but I think we'll see him again in Italy," he concluded.
