Below: strengths, watch-points, market-value outlook and the latest transfer news on Kostka.

Year-on-year, that's broadly in line with last season (Season 6 → 8).
On long-term talent our Rating reads 40, top 34% of the 48 full-backs in the 3. Liga. At 22 Kostka is still climbing toward his ceiling, and a market index of 19.8 reflects that trajectory.
Kostka is operating at his career peak — the 2025/26 level is the level.
3.24 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 25 appearances. Behind an upper-table side (3rd of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume.
With a Rating of 40, Kostka carries the 16th-highest potential of the full-backs in the 3. Liga of 48 — though on just 25 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (3.24 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead.

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 (~21), then tapers with age. At 22, Kostka sits on 19.8, still climbing toward its peak. The blue line is Kostka's projected Rating — 40 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.
