How do European squad lists work?

What the report says

BBC Sport explains how European squad registration works for the Champions League, Europa League and Conference League after clubs meet a Uefa deadline for submitting their senior player lists. The article says teams must file a 25-man List A, with at least eight locally trained players, alongside a separate List B for younger players that can be updated up to the day before each match.

The report outlines the main eligibility rules for List A and List B, including how Uefa defines club-trained and association-trained players, and why clubs can lose squad places if they do not meet the locally trained quota. It also notes that goalkeepers are treated differently from outfield players, with more flexible replacement rules if they suffer long-term injury or leave the club.

BBC Sport says List A is largely fixed for the league phase, but clubs that reach the knockout rounds can add up to three new players by a later February deadline. The piece also says emergency changes can be made in some injury or illness cases before matchday six, and that transfers can create timing issues for clubs in leagues whose windows remain open after Uefa’s registration cutoff.

The article adds helpful context by comparing Uefa’s homegrown rules with domestic league rules, using examples from clubs such as Arsenal, Bayern Munich, Celtic and Hearts to show how the system affects squad planning across Europe.
