Inter Milan chief Piero Ausilio rapped the attitude of their players after yesterday's 1-1 draw with Parma.
Fredy Guarin struck for Inter in the disappointing result.
"The team will train tomorrow at 08.30 am, seeing as they rested today," an irritated Ausilio told Sky Sport Italia.
"Tomorrow they will turn up after a night of reflection. Mancini took responsibility? It's everyone's fault, not just the Coach.
"There are examples around of good football with limited resources, so these are the ideas we are taking forward. We look to the present and future, as along with Mancini we are doing the right things to reinforce Inter."
