Level is the average rating of each league's clubs on the global scale (attack + defence, from closing betting-market prices). The goal ratio is what the gap means on the pitch: goals an average club of the stronger league scores for each one it concedes to an average club of the other, on neutral ground. The record is every Champions League, Europa League and Conference League meeting between the two leagues' clubs — their best sides, over seasons the ratings have moved past, so it is history, not the measurement.
As of 28 October 2026, Serie A is stronger than the Primeira Liga: an average Serie A club would score 1.79 goals for every one it concedes against an average Primeira Liga club on neutral ground. In European competition since 2022-23, Serie A clubs have won 15, drawn 11 and lost 6 of 32 meetings with Primeira Liga clubs.

Serie A vs Primeira Liga in Europe
Every Champions League, Europa League and Conference League meeting between Serie A and Primeira Liga clubs since 2022-23, counted from the Serie A side. Each club is placed in the league it played in that season. Euro clubs are each league's best, not its average, so this is history beside the rating, not part of it.
