The Nerazzurri defeated Antonio Conte's side to end their 49-match unbeaten run.
"I do not think losing means we will have lost our confidence," he told La Stampa. "We have been growing as a team for over a year, and sooner or later the run had to come to an end.
"The win will of course give Inter more self-belief, but I don't think it affects us too much. For the first quarter of the game we played well, looking for the second goal.
"But we sat back a bit too much and defended with fear. I don't like losing, but my discomfort towards the result is only mild."
