The forward has revealed that he has a "great relationship" with Walter Mazzarri and that there was an outside chance he could have moved to the San Paolo
The Italy international only joined the Rossoneri from city rivals Inter during last year's summer transfer window but he has revealed that there was the possibility of him moving to the San Paolo before the start of the current campaign.
"I have a great relationship with [Napoli coach Walter] Mazzarri and there was something during the summer, but it was a road that didn't lead anywhere," he explained in an interview with La Gazzetta dello Sport.
As it is, Pazzini now looks certain to lead the Milan attack this weekend, with Mario Balotelli ruled out through suspension.
With the Rossoneri currently four points adrift of their second-placed rivals, the striker is under no illusions about the enormity of the game.
"A team like Milan must always be in the Champions League. Always," Pazzini declared. "And I have said this: if we lose against Napoli, second place would become almost impossible.
"Simply put, we have to win. But we'll be ready."
Pazzini is also desperate to prove his worth - not only to Milan coach Massimiliano Allegri but also Azzurri boss Cesare Prandelli.
"If I can do well next season, like I have done this year, the World Cup will come for me," he reasoned.
"So, I would still make the decision to come here 100 times over."
Milan's eagerly-awaited meeting with Napoli at the Giuseppe Meazza will get under way at 20:45CET.
