Inter Milan captain Javier Zanetti says they cannot dwell on yesterday's defeat to Cagliari.
Inter now have AS Roma in the Coppa Italia semifinal on Wednesday.
"Where we will go from here? We want to play well against Roma on Wednesday," responded the captain. "There's no point talking about this match, we can't do anything about it, we've missed an opportunity. Now we need to think about performing well on Wednesday.
"The referee got the penalty decision all wrong? We're gutted about the result, and it makes you angry. But it's at times like these that we find the strength to move on and become a better team."
