Balotelli could make his debut tonight against Udinese.
"First of all, I want to compliment Massimiliano Allegri for forging a team that is very different to last year, packed with youngsters and still battling for the top spots," said Guidolin in his Press conference.
"Balotelli has the potential to become a top player. It is important for Italian football that we recovered a talent like him. Obviously he will generate a lot of enthusiasm, but we mustn't forget players like Giampaolo Pazzini who can also make their mark."
