"If you look at last week's result, it was a good result," Rutten said.
"In reality we were fortunate to get the draw. That result is not a guarantee of making the next round.
"We'll play to win the game. We're playing a team which knows how to wait and that can strike a killer blow at any time.
"It will be even more difficult that the first leg.
"Dutch players always want to play against the Italians, and it's always down to small moments to decide the game.
"We all know we had a good result [last week], we did well, but we're no longer thinking about it. We have to think about the next game.
"We want to go forward and qualify for the next round."
