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.

- the CC0 Transfermarkt community mirror; a market-consensus quality prior, taken at a capped weight where it reads a player higher than our (fixed, partial) shot/event data can
- the arithmetic
- 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.

What he’d cost · our estimate
€2.2m–€8.6m ≈ €4.4m
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.
