Year-on-year, that's a drop on last season (Season 26 → 0). Over the 3 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 9. At 32 Jach is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.5 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
0 tackles, blocks & interceptions per 90 — light defensive volume across 16 appearances. Doing that for a relegation-threatened side (16th of 18) 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. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
Rated 8.9 overall — below regular-starter level. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.8× and falling).

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 (~1), then tapers with age. At 32, Jach sits on 0.5, past its peak and easing. The blue line is Jach's projected Rating — 8.9 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.
