The Brazilian hit-man has been playing well for his side and he is quickly becoming a star at San Siro.
Pato is likely to start against the Partenopei in tomorrow night's crunch match and he cannot wait to make his mark as Milan continue their Scudetto hunt.
"My most amazing experience so far was my first training session with Milan," Pato told La Gazzetta Dello Sport.
"I remember walking onto the pitch at Milanello surrounded by all those champions and I thought, 'Mamma mia!'
"This season we are aiming for the Scudetto and UEFA Cup, these are our main ambitions.
"Napoli? I can't wait to play. My first game for Milan was against them in January and it was an unbelieveable experience.
"They have great players like [Eziquiel] Lavezzi and [Marek] Hamsik. However, we have three Golden Ball winners in our team so it should be a good game on Sunday."
Pato then spoke about the failure to qualify for the Champions League and his ambitions to win the Ballon d'Or in future.
"The biggest delusion was not qualifying for the Champions League it was a shame but never mind, we move on.
"In future I would like to win the Ballon d'Or, I have great examples to follow here at Milan."
The Rossoneri are just one point behind league leaders Napoli heading into Sunday night's crucial match. This game could launch Milan in firm command at the top of the table as they fight for the Scudetto.
