the ± is how settled the number is, more minutes, tighter band

at or near his peak, no projected upside from age

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 +34 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.

measured: 18.00 transfer market value (EUR millions), as a rank among peers
his rank: 97th percentile of qualified peers
scored from: 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(96.6th) = 46 × 1.83 × 0.4 (position weight) = +34

A forward-only shadow signal, as of 2026-06-23. 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.

The folded nights have added +27 to the number he seeded with, he has outplayed his own prior.

What he’d cost · our estimate

We don’t price him yet. Our fee model leans on the level he plays at, and no trusted source has given us his club’s strength. We’d rather show nothing than a number we don’t trust.

The fee record · sourced

The market’s last public word: €16m (2021-07). The gap is evidence, many of them, together, recalibrate our model; no single one rewrites him.
