Inter slipped to sixth place in the Serie A table as two goals from Marco Di Vaio and another from Robert Acquafresca condemned Ranieri's side to a fourth league defeat from their last five matches.

"We are not giving our all," Ranieri told Sky Sport Italia after the match. "We are going through a difficult moment."

"We must take responsibility and apologise to our fans and the president."

"We expected a difficult match, but never with this outcome."

Asked if he was thinking about resigning from his post, Ranieri said: "I am not planning anything. We are all united in trying to find a solution to these problems."

Inter have conceded 12 goals in their last four matches prompting Ranieri to single out defensive fragility as a key cause of his side's slump.

"We had found a balance and a good tactical unity. But we have lost this now and we concede goals at the first opportunity from our opponents."
