Palermo President Maurizio Zamparini claims he didn't sleep a wink after Monday's 1-0 defeat to Napoli at the San Paolo.
The Rosanero looked all set to take a point back to Sicily with them, only for Christian Maggio to score a 95th minute winner for the home side.
"I didn't sleep the entire night. I watch the game again twice," Zamparini said. "Napoli deserved it. They were superior. They created several chances and in the end they took the three points.
"It's not a problem with the formation. Against Napoli the problem was not Javier Pastore, but our full-backs Federico Balzaretti and Mattia Cassani who got the game wrong."
Looking ahead to this weekend's clash with Parma, he said: "It's a difficult game. We are dealing with one of those games that you think you can win and then lose. We have to be careful."
