The young tactician has praised upcoming opponents Torino, but insists his side must strive to avoid any more slip-ups if they are to challenge for the Serie A title
Il Toro are yet to taste defeat this season, comfortably disposing of Pescara with a 3-0 victory in their last outing.
Inter, meanwhile, were outclassed by Roma heading into the international break as they succumbed to a 3-1 defeat.
And Stramaccioni, speaking at a press conference ahead of Sunday's fixture, has conceded the Nerazzurri must avoid making similar mistakes if they are to leave Turin with a win.
"[Torino] is an opponent that we respect. They are in great form, haven't conceded yet and are in high spirits. We know it will be tough, but we want to win again," the 36-year-old began.
"We cannot make mistakes [like the ones leading up to Roma's second goal]. But I'm sure we have learned from those mistakes."
He went on to comment on the fitness of some of his injured players, who were given time to recover during the recent international break.
"The break was important to improve the overall condition of the group. We have worked hard, and are ready for the run of important and tight matches that lie ahead."
"[Cristian] Chivu has returned to group training for the first time. [Dejan] Stankovic should recover and with him we will have to be especially careful," the Italian concluded.
Kick-off for Sunday's encounter is scheduled for 18:45 UTC.
