Palermo president Maurizio Zamparini is angry with his defence after their thrashing by AC Milan.
Zamparini branded the performance as "embarrassing".
"I spent around €16m on Andrea Mantovani, Matias Silvestre and goalkeeper Emiliano Viviano and I’m still seeing defensive errors," he said.
“We have the third worst defensive record in the League now. We have to play with more attention out there.”
