"Let's say it's a good start, but we know there are things we still need to work on," said Stramaccioni after the game on Sunday.
"It's good that we have followed up Thursday's performance [against Vaslui] with another decent one tonight.
"Our quality comes through when we move the ball around. It was a good start but there's a long way to go. We have to keep our feet on the ground."
Inter are back in Serie A action next Sunday when they host Roma at San Siro.
