The Italian has shown glimpses of brilliance since his move from Inter Milan in 2010 but is often in the headlines for all the wrong reasons.
In recent times, Balotelli's form has been less than impressive but Toure believes he can still be a superstar of the English game.
"Mario is an unbelievable player, but sometimes he can be angry with himself," said Toure told the Manchester Evening News.
"All players need to improve, and I talk all the time with Mario.
"This year especially he has been working hard in training, and improving well, but sometimes in the game you can get so disappointed when you lose small things.
"But he has fantastic character, and I know he will be one of the top strikers in the Premier League."
