Palermo president Maurizio Zamparini was furious with their defeat to struggling Bologna on Sunday.

It was their third consecutive game without victory and left Zamparini fuming with coach Walter Zenga.

"Zenga has spoken about individual errors in the defence, but he has to teach them not to repeat certain blunders," Zamparini explained.

"We have a defence with an international in Kjaer with Bovo and Cassani who are both very good players. If the offside trap doesn't come to be applied well, like for Bologna's second goal, it means to say that you haven't worked hard enough on this aspect - eight goals conceded in just two away games. Here is why I am worried."

Asked if that meant he was considering sacking Zenga, Zamparini replied: "I am tied to him. I feel affection. I consider him like a son. He is a capable and loyal person. But results count here. In the end words are not enough. I agree with Zenga when he talks about 'the law of the League table'.

"If in the next nine games this turn of events continues, we'll be set for relegation."
