Balotelli has taken the brunt of criticism for Italy's World Cup failure.
"I'd love to have a talk to Mario... If I were his Coach, I'd treat him the same way I did players like Strunz, Edmund and Antonio Cassano, all difficult guys who I can modestly say I put on the right path.
"I spoke to them like a father. I'd knock on the door at midnight, ask if they were sleeping and give important advice.
"I also had a player in the Irish national team who gave me big problems, but I resolved them."
Trap warned there is too much expectation on Balotelli's shoulders to deliver a world class performance.
"He is potentially a champion, but not a real Champion with a capital C. I worked with a few of those: Platini, Tardelli, Scirea, Boniek, Bettega, Causio, Matthaus."
