Seeded from his team’s rating, then moved by the matches he actually played. A shadow signal, it never touches a live call.

Where the +44 was earned

The earned line, opened up by competition. World Cup finals count 1.5×, qualifiers and cups 1×, friendlies and club football half, so a tournament night moves him most.

2026-05-16club football · 72′ · team result only▲ +1

Each night’s move blends his team’s result with his own match stats, saves for keepers, tackles and duels for defenders, creation for midfielders, finishing up front. “Team result only” marks games where the feed carried no player stats.

A forward-only shadow signal, as of 2026-06-27. 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.

At this World Cup

What the tournament has done to his rating since the first whistle on 11 Jun, and the matches behind it. Each night’s move blends his team’s result with his own performance, shrunk for sample size, so a strong game nudges the number rather than spiking it.

What he’d cost · our estimate

€5.1m–€20m ≈ €10m

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.
