Contrary to LAM's reply, yeah. It's always talked about throughout Serie A circles since it consistently happens, that the tightest defence wins the title.
It probably takes effort to look up*, but if anyone did, they'd see that time, and time, and time, and time, and time again, in a row, the Serie A league winners have the fewest goals conceded; it takes an absolute freak of nature to create an exception to the rule. *(Just checked - 14 seasons out of the last 15, the rule I posted applies.)
Although it's a lazy name, Serie A hasn't been branded 'the defensive league' for decades for no reason.
