The Serie A champions have struggled so far this season under new coach Rudi Garcia, with players seen squabbling between eachother.
Di Lorenzo, after the Bologna stalemate, said: We are certainly not happy with the result, the mood is not the best because we wanted to return to victory.
"We must immediately think about the next one which is in a few days. We must improve our management of the match, sometimes we lack continuity and we must immediately put it right.
"It is certainly a moment where things are not going well and some reactions stand out a little, we will talk about it to avoid these attitudes. In these moments these attitudes are not needed.
"We will talk to each other to try to improve this situation. It's a new year, a new campaign with a new coach but the group is united and we will work to get out of this situation."
