City are seemingly keen to bring the hot-headed young striker to Eastlands this summer for a fee of around £25million while Inter are thought to be willing to let Balotelli go after a string of fall-outs with team-mates and management.
And Cameroon striker Eto'o, himself notoriously tempestuous, told the Daily Star Sunday: "He has the potential to go on and be one of the best players in the world but he must sort some things out in his head.
"The older players at Inter Milan have always tried to advise him. I am not sure how successfully but, if he is to be a success and not waste his career he must listen to the players at Manchester City. This is the chance for a fresh start."
