Nationality does work here that it does nowhere else in the family. A group of four born in the same country is common, and because the club game is international it rarely overlaps with the club groups sitting beside it. The rest is clubs — those a player turned out for, and the one where he broke through.
Yes. Winning a continental championship or a major international honour is its own group, which puts four players from the same victorious generation together regardless of where they spent their club careers.
No. The rotation is built from the whole record it can verify, so clubs from several countries appear, and a nationality group frequently reaches outside Europe entirely.
Four players who never moved — one club from breakthrough to retirement. In a sport defined by transfers it is a rare enough career shape to be a genuine category, and it is a group that punishes anyone guessing from a player’s most famous season alone.
Because the sport has no draft. That single structural difference is why this board reads unlike the American rotations: players arrive through academies and transfers, so the board asks where someone came through rather than where they were selected.
