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 2026-06-29. 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 lines a beat writer keeps, except every one of ours is read off the ledger above, auditable to the night. Nothing invented.

What he’d cost · our estimate

€3.6m–€14m ≈ €7.2m

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.
