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.

A forward-only shadow signal, as of 2026-06-25. 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

€2.5m–€9.8m ≈ €5m

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: €5m (2022-07). Our estimate today: ≈ €5m. The gap is evidence, many of them, together, recalibrate our model; no single one rewrites him.
