Atalanta shocked Inter 4-3 on the day.
"We played the perfect game in the second half and won a spectacular match," Polito told ItaSportPress.
"I will just say that Inter are a big club and can't be complaining about a penalty awarded to Atalanta, especially as they were still 3-2 up after that goal. That would be a huge mistake.
"They should instead focus on their own problems, seeing as they went from 3-1 to 3-4 in 12 minutes against a team of a much lower stature.
"If we want to really pick at every decision, then I'll point out on Inter's second goal there was a foul on Guglielmo Stendardo that nobody noticed.
"I was on the pitch that night and what I saw was an Inter side set out badly and with no ideas."
