"It's too easy to play great football against Milan," Zampa yelled on Radio Anch'io Sport. "We were well-motivated last night and we have great players who can take on anyone if they are determined enough on the pitch.
"That's how we were able to shock Juventus at the Stadio Olimpico and how we managed to beat Milan.
"It was a really good Palermo performance, even though we can't forget that Milan were missing Kaka and Gennaro Gattuso.
"It was a wonderful night for us, but we have to repeat this performance against Cagliari next weekend."
