D'Aversa admits they weren't competitive on the day.
“We conceded the first goal from a set play and in the second there were eight of us behind the ball, yet we let it through anyway. Clearly we lack determination and need to get it back as soon as possible," the coach told Sky Italia.
“When we concede two goals the way we did today, we have to take a good hard look at ourselves. Parma climbed back from Serie D with determination and hunger. Now those elements are lacking.
“The only positive is that we can't do worse than this, so the only way is up. There's no point hiding from the difficulties we face.
“After a good week of work in training, I didn't expect a performance like this. There are 17 games to go, we are only three points off the safety zone, so we need to knuckle down. There's a long way to go."
