Andrea Sottil was angry with the nature of the goals his team conceded in their 2-2 draw with Spezia on Sunday.
"We cannot be conceding two goals like that," he said. "We turn a difficult match around and are in complete control, then we concede from a counterattack. I will no longer tolerate this."
"I'm dismayed and also very angry. It's our fault today and it's me in charge. We could have committed a foul [before the equaliser] but failed to. We're giving points away."
The coach added: "The team is working in a serious matter but we're the ones determining results. With 20 minutes to play, in the lead and in total control, you cannot give away yet another equaliser.
"We must not be afraid, we have to bring out our craft and experience. A team like ours cannot concede these goals. We only have ourselves to blame for not winning this game."
