Where the +58 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.

the arithmetic
46 pts/σ × z(99.9th) = 46 × 3.16 × 0.4 (position weight) = +58

A forward-only shadow signal, as of 2026-06-22. 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.

  • standing

    #4 of 1424 on our board, inside the top 1% of everyone we rate.

  • vs his seed

    The folded nights have added +24 to the number he seeded with, he has outplayed his own prior.

  • workload

    He barely leaves the pitch: 87′ a night across 32 folded appearances.

What he’d cost · our estimate

€16m€61m €31m

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.

The fee record · sourced

The market’s last public word: €30m (2019-07). Our estimate today: ≈ €31m. The gap is evidence, many of them, together, recalibrate our model; no single one rewrites him.
