Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1 goal in 12 appearances (0.08 per game) — light end product the role wants to see climb.
Rated 50.7 overall — a solid contributor and squad regular. In the final third he profiles as a work-in-progress on end product (0.26 goal contributions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~19), then tapers with age. At 24, Kania sits on 19.3, at or near its peak. The blue line is Kania's projected Rating — 50.7 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
