Where he starts (his team’s strength, we refuse to invent what we haven’t measured) plus two fixed nudges make the quality rating above; the last line is what national-team results have added since, taking it to his full roster Elo.

Where the +21 skill term comes from

Not a reputation, a measurement. We score every shot in the data ourselves and rank him among minutes-qualified peers; a fixed arithmetic turns that rank into points.

46 pts/σ × z(86.8th) = 46 × 1.12 × 0.4 (position weight) = +21

A forward-only shadow signal, as of 2026-06-24. The skill term comes from our own xG models over the open archive; the rest is earned, recorded per appearance, auditable, never back-filled. It never moves a live call.

The notebook

The lines a beat writer keeps, except every one of ours is read off the ledger above, auditable to the night. Nothing invented.

Not a figure from any valuation site; we don’t republish those. Our own model: the level he plays at, what we’ve measured of him, his age and his role. A band, not a point: we can’t see contract length or release clauses, the two biggest real drivers, so we say so.

fee-model v3 priors (panel-anchored, 2026-06), calibrated against our reported fees. The band is roughly two-in-three likely; contract length and release clauses are data we don’t hold. Context only, it never touches a call.
