Icons — Roman numerals (Ⅰ, Ⅱ, Ⅲ) mark competition levels. Level Ⅰ is the top continental tournament on each continent — UEFA Champions League in Europe, Copa Libertadores in South America, AFC Champions League Elite in Asia, CAF Champions League in Africa. Level Ⅱ is the second-tier continental competition — UEFA Europa League, Copa Sudamericana, and equivalents. Level Ⅲ is the third tier where it exists, with the UEFA Conference League as the defining example. The star (★) marks championship counts; the plus (+) marks statistical totals. The list icon (☰) opens a filtered club or player list. The trophy icon opens a full title breakdown. The info icon reveals additional details — host cities, historical notes, and broadcast links. The home icon marks a player entry; the key icon marks a manager entry.
