Palermo president Maurizio Zamparini is furious after their Coppa Italia defeat to Modena.
The Sicilians were knocked out of the competition with a humiliating 3-0 home defeat.
"Beppe Iachini performed two or three experiments with Milan Milanovic and Zouhair Feddal, but these choices proved to be unwise," Zamparini told La Repubblica.
"The team that plays in Serie A next weekend cannot be the one we saw last night losing to Modena, a side that finished 25 points behind us in Serie B last season.
"We simply can't play like this in Serie A."
