Adrian Mutu and Alberto Gilardino hit the goals for the Viola and Prandelli said: "We have had a good first-leg, now it will not be easy in the return.
"But the spirit was right, the team has responded well as has the public. I am satisfied with the performance."
Mutu added: "I had no doubts, Alberto has always done well. He's a serious player and has always had goal sense."
