Clean sheets

4.36 tackles, blocks & interceptions per 90 — solid defensive volume across 15 appearances. Doing that for a relegation-threatened side (17th 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.

Strengths

Defensive volume. 4.36 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 35.7% of available minutes — needs a settled run to prove the level.

Outlook

Rated 56.8 overall — a solid contributor and squad regular. Defensively he reads as solid defensive volume (4.36 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around. 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 (~34), then tapers with age. At 26, Siersleben sits on 33.9, at or near its peak. The blue line is Siersleben's projected Rating — 56.8 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.
