Palermo President Maurizio Zamparini has once again criticised Delio Rossi, telling reporters that he is poor when it comes to coaching the defence.
Zamparini was particularly embittered at the weekend after Palermo threw away their lead against Inter and ended up losing 3-2.
"Rossi went to sleep a little in Milan," Zamparini said. "He got it wrong. He is Zeman-like in attack, but poor in defence.
"This team would do well with any Coach, but it doesn't have a mentality. The Coach must give it one, just like Walter Mazzarri is doing at Napoli, not the club.
"The formation should be adapted to the players. Udinese are doing very well with a 3-5-2, which I have recommended to my Coach, but I am taken for a madman.
"Rossi is a maestro in training during the week, but he must improve tactically on a weekend. I hope that he improves.
"Sometimes it's impossible to have a dialogue with Coaches who think that they have invented football," Zamparini concluded.
