Clean sheets

6.26 tackles, blocks & interceptions per 90 — high defensive volume across 2 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. 6.26 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 12.2% of available minutes — needs a settled run to prove the level.

Outlook

Rated 52 overall — a solid contributor and squad regular. Defensively he reads as high defensive volume (6.26 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 (~31), then tapers with age. At 26, Siersleben sits on 31.1, at or near its peak. The blue line is Siersleben's projected Rating — 52 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.
