Trapattoni worked with Edmundo at Fiorentina.
"Balotelli reminds me of Edmundo," he told Radio Anch'io Sport.
"I used to talk with him until one or two o'clock in the morning to try and understand what was his problem.
"He used to say 'yes, yes' to me and then he'd take to the field of play and argue with Gabriel Batistuta and Manuel Rui Costa
"Italy boss Cesare Prandelli is good, but he has to be aware as some players carry the risk of snapping the balance within a team."
