Prandelli said: "I consider him to be a centre-forward. Now he is working hard in the penalty area and is slowly finding the cool head needed to turn all that effort into goals."
Mariano Santana and Adrian Mutu both struck before Pazzini's effort. Genoa youngster Nicolas Masiero grabbed his first goal for the club in the final ten minutes.
Prandelli continued: "Genoa were vivacious and dangerous throughout, so we only emerged with this win by playing very good football. We struggled at the end, but we were tired. I have to say my team is always very generous.
"I liked the fact we never stopped attacking even after taking a strong lead."
"The fight for fourth will be very tough. I saw Milan play last night and they are right back on form, so they could definitely win every remaining game."
Genoa Coach Gian Piero Gasperini had no complaints about the 3-1 defeat in Florence, although he did note an unfortunate trend.
"When facing the big clubs we are always lacking something to cause an upset. We put in good performances, but just can't seem to get the results.
"We certainly have some limitations in that respect and have to focus on achieving safety as soon as possible."
