On long-term talent our Rating reads 40. At 17 Donmezer is still climbing toward his ceiling, and a market index of 17.8 reflects that trajectory.
0 clean sheets in 4 appearances (0% of games). Keeping that many behind a relegation-threatened side (20th of 20) — a side that concedes more — points to a busy, productive season between the posts.
Rated 39.8 overall — developing / rotation level. A limited game time keeper carrying the gloves this season. At 17 the trajectory points up — potential sits near its ceiling (100/100) and market value should climb as minutes and output follow.

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 (~26), then tapers with age. At 17, Donmezer sits on 17.8, still climbing toward its peak. The blue line is Donmezer's projected Rating — 39.8 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.
