Palermo president Maurizio Zamparini has already turned on new coach Bortolo Mutti.
So far Mutti has managed a 2-2 draw at Novara and 3-1 home defeat to Napoli.
"Mutti made a huge tactical error by transforming the side between the first and second half," slammed Zamparini on Mediagol.
"It's a situation and some mistakes that I never want to see again."
