Club football data methodology
Kickoff Lens is extending the World Cup proof of work into a durable club-football database for the UEFA Champions League, Premier League, La Liga, Serie A, Bundesliga, and Ligue 1. The goal is not to mirror official sites. The goal is to give readers one consistent way to understand team strength, squad depth, schedule pressure, tactical fit, and post-match change across competitions.
This methodology page is the public release contract for that work. It explains what must exist before club, player, and matchweek pages become indexable, which fields are planned, which sources can be used for verification, and which rights-sensitive materials are excluded.
Current release state
| Layer | Current public state | Search policy |
|---|---|---|
| World Cup database | Active match, team, player, venue, and knockout pages with live-agent-first data. | Indexable where the page contains useful confirmed context. |
| Competition themes | Indexable planning pages for Champions League and five major European leagues. | Included in sitemap as durable database-entry pages. |
| Club dossier prototypes | 48 seed club pages showing the future structure, fields, radar dimensions, and release gates. | Noindex, follow until source-backed dossier fields are complete. |
| Matchweek and player club pages | Not generated yet because fixture ingestion and player-source coverage are not production-ready. | Excluded from sitemap until they pass release gates. |
Five-league coverage model
UEFA Champions League
cross-league club comparison, travel pressure, rotation depth, and knockout-stage matchup reads.
First modules: cross-league strength comparison, travel and rest load, league-phase pressure.
Premier League
pressing intensity, squad depth, European-competition rotation, and fixture congestion.
First modules: pressing and recovery profile, fixture congestion and European rotation, top-four and relegation pressure.
La Liga
possession control, technical chance creation, table pressure, and European-place races.
First modules: possession control profile, chance quality and press escape, Clasico and derby context.
Serie A
defensive structure, chance suppression, tactical matchups, and rotation patterns.
First modules: defensive structure profile, chance suppression and set-piece load, low-margin tactical recaps.
Bundesliga
transition speed, pressing lanes, youth impact, and high-tempo fixture context.
First modules: transition speed and pressing lanes, young-player impact tracking, high-line exposure.
Ligue 1
talent development, pace profiles, club depth, and European qualification context.
First modules: talent development watch, pace profile and transition defense, European-place pressure.
Club dossier scorecard
A club dossier becomes useful only when it gives readers more than a name and a schedule. The first indexable version should include the following layers.
| Scorecard layer | Reader value | Required evidence |
|---|---|---|
| Identity and competition context | Explains the club's league, European status, and current database scope. | Public club/competition page, visible update timestamp, no logo or crest dependency. |
| Strength radar | Shows how the club is read across pressure, chance creation, control, defense, depth, and schedule load. | Transparent dimension labels and a note on source coverage. |
| Squad and availability frame | Separates confirmed absences, rotation load, and role dependency from unsupported rumors. | Public match reports, club updates, or credible fixture notes; no private or scraped injury claims. |
| Matchup fit | Connects the club to specific matchup types, such as pressing-versus-build-up or European-workload rebound games. | Original editorial analysis and source-backed context. |
| Post-match archive | Keeps pages valuable after full time by preserving what changed, not just the score. | Confirmed final result, event availability note, tactical recap, and correction path. |
Indexing release gates
Pages stay outside the sitemap until they clear these minimum fields. This prevents the site from publishing empty club, matchweek, or player pages just to increase URL count.
| Page type | Minimum fields | Why it matters |
|---|---|---|
| Club dossier | club name as text, competition, style profile, radar axes, squad depth note, player-dependency note, source timestamp, rights boundary | Prevents thin pages and keeps source-backed reader value visible. |
| Matchweek brief | home club, away club, kickoff window, venue or city, table implication, rotation/rest context, strength comparison, source timestamp | Prevents thin pages and keeps source-backed reader value visible. |
| Post-match recap | final score, result confirmation source, event availability note, table effect, model-read comparison, correction timestamp | Prevents thin pages and keeps source-backed reader value visible. |
Radar dimensions by competition
Kickoff Lens keeps a common interface but changes the weighting and explanation by competition. A Champions League away tie is not read the same way as a domestic derby or a congested league matchweek.
| Competition | Primary radar dimensions |
|---|---|
| UEFA Champions League | Cross-league strength, Away travel, Rotation depth, Transition threat, Set-piece pressure, Knockout control |
| Premier League | Pressing resistance, Chance creation, Defensive control, Rotation depth, Fixture congestion, Table pressure |
| La Liga | Possession control, Chance quality, Press escape, Defensive block, Squad continuity, Derby pressure |
| Serie A | Defensive block, Chance suppression, Build-up control, Wing progression, Rotation stability, Set-piece load |
| Bundesliga | Transition speed, Pressing lanes, High-line exposure, Chance tempo, Youth impact, Rest load |
| Ligue 1 | Pace profile, Talent development, Transition defense, Squad depth, European-place pressure, Away control |
Source and rights boundary
Kickoff Lens can use public facts and names for factual identification, but it does not copy official databases or import protected visual identity. The site will not publish official league marks, club crests, kit images, trophy art, mascots, broadcast screenshots, video clips, official article copies, ticketing claims, livestream links, or paid-tip language.
Official and primary links on competition pages are provided for verification and transparency. They are not affiliation claims, partnerships, media-rights claims, or data-feed licenses.
What ships next
- Keep World Cup data stable while the knockout phase continues.
- Convert the strongest club prototypes into source-backed dossiers only when the release gate is met.
- Add matchweek briefs after fixture ingestion, source timestamping, and update cadence are reliable.
- Add player club pages only when role, minutes trend, availability, and source notes can be maintained without scraping protected material.
