Clean sheets

3.32 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 21 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. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.

Watch points

Game time. Only 49.9% of available minutes — needs a settled run to prove the level.

Outlook

Rated 70 overall — elite — among the best in the position. Defensively he reads as moderate defensive volume (3.32 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

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 (~43), then tapers with age. At 24, Siebert sits on 43.3, at or near its peak. The blue line is Siebert's projected Rating — 70 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.
