Palermo president Maurizio Zamparini admits his coach sackings is costing the club.
New arrival Gian Piero Gasperini makes his debut for the Sicilians against Atalanta today.
"If I thought about the money I've spent on Coaches, I'd feel like shooting myself," Zamparini told Tuttosport.
"It must be more than 10m, 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 to Coaches.
"The wages should be a maximum of 100,000. It's ridiculous that working as a Coach for three years means you never have to work again."
