Below: strengths, watch-points, market-value outlook and the latest transfer news on Köşker.
On the season, Köşker graded 1 for current form (age-blind), on 0 goals, 0 assists and 3.214 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 0 → 1).
On long-term talent our Rating reads 37. At 23 Köşker is still climbing toward his ceiling, and a market index of 23.5 reflects that trajectory.
3.21 tackles, blocks & interceptions per 90 — moderate defensive volume across 2 appearances. Doing that for a lower-table side (17th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight.
Rated 36.7 overall — developing / rotation level. Defensively he reads as moderate defensive volume (3.21 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) 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 (~24), then tapers with age. At 23, Köşker sits on 23.5, at or near its peak. The blue line is Köşker's projected Rating — 36.7 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.
