Outlook

With a Rating of 21.1, Köstl carries the 14th-highest potential of the centre-backs in the Super Liga of 25 — though on just 22 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.11 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

Market valueRating

Solid = now · dashed = projected

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 (~2), then tapers with age. At 28, Köstl sits on 1.5, past its peak and easing. The blue line is Köstl's projected Rating — 21.1 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.
