The Rossoneri endured a torrid time over the last campaign and they finished the season a disappointing eighth in the table.
Their failure to qualify for Europe led to Clarence Seedorf's dismissal as manager, but new boss Inzaghi has been encouraged by their displays in pre-season.
"My staff and I are confident, we are seeing good things in the eyes of the players," he told reporters.
"We need to be at 100 per cent for the first match of the season."
Inzaghi spent 11 years playing for Milan and scored 126 goals for the club.
