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 +18 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(83.2th) = 46 × 0.96 × 0.4 (position weight) = +18

A forward-only shadow signal, as of 2026-06-20. 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

    #1091 of 1424 rated players on our board.

  • vs his seed

    The folded nights have added +33 to the number he seeded with, he has outplayed his own prior.

  • workload

    He barely leaves the pitch: 86′ a night across 27 folded appearances.

What he’d cost · our estimate

€1.4m€5.4m €2.7m

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.
