The 71-year-old Palermo chief is known for not giving his coaches much time to impress, and has already sacked Giuseppe Sannino after just three Serie A games this term.

"If I thought about the money I've spent on coaches, I'd feel like shooting myself," he told Tuttosport.

"It must be more than 10 million euros, as I've been firing people for 25 years. What really hurts me is that a factory worker won't earn 1m in his entire life, so we ought to give much less (money) to coaches.

"The wages should be a maximum of 100,000 euros. It's ridiculous that working as a coach for three years means you never have to work again."

Current coach Gian Piero Gasperini has his first game in charge of Palermo against Atalanta on Sunday.
