The person's existing knowledge: [which league they already follow and at what depth]

1. Structural features: how the league is organised, typical season rhythm, number of promoted and relegated clubs
2. Tactical identity: the dominant playing style or styles this league has produced or favoured
3. Financial and competitive balance: whether title races are genuinely open or effectively closed
4. Cultural character: how the league is experienced by fans and what makes attending it distinctive
5. What the league produces: what quality of product it exports to European competition and player development

**Grounding rule:** describe current characteristics and well-established patterns, noting where things have changed recently.
