Attackers create obvious moments that travel well across highlights: goals, assists, shots, and carries. Defenders and goalkeepers often create value by preventing events before they become visible.

That difference matters for public valuation. A centre-back who improves rest defense, wins duels, and starts attacks may be essential, but those actions are harder to summarize in one number.

Goalkeepers are even more specific. Shot-stopping, claiming crosses, sweeping behind a high line, and passing under pressure can fit one club perfectly and another club poorly.

The best way to read defensive value is to compare role and context. Age, league level, build-up responsibility, aerial strength, and international experience all help explain why some defenders break the usual ceiling.
