A Giacomo Bonaventura volley and Dusan Vlahovic's effort had the Viola 2-0 ahead before Nwankwo Simy pulled one back in the second half.
“We played well, fought for every ball, remained concentrated and got the win even though we tried to over-complicate matters in the second half," Prandelli told DAZN.
“In modern football, you have to be aggressive and get the ball back when the opposition has it. Quality is wonderful, but it means little without determination and aggression, so we need to use both elements, especially in our current position.
“The quality must also never take over from teamwork. It has to be used in favour of the team, to create chances and play our way forward. I am pleased that for the most part, we did that today."
