Clean sheets

3.75 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 10 appearances. Doing that for a relegation-threatened side (20th 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 0 goals and 1 assist — a useful bonus from the back.

Strengths

Defensive volume. 3.75 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 21.1% of available minutes — needs a settled run to prove the level.

Outlook

Rated 47.1 overall — a solid contributor and squad regular. Defensively he reads as solid defensive volume (3.75 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow.

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 (~22), then tapers with age. At 21, Alders sits on 12.5, still climbing toward its peak. The blue line is Alders's projected Rating — 47.1 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.
