Clean sheets

4.3 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 3 appearances. Doing that for a lower-table side (18th of 24) 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. 4.3 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 6.1% of available minutes — needs a settled run to prove the level.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 35.6 overall — developing / rotation level. Defensively he reads as solid defensive volume (4.3 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~8), then tapers with age. At 25, Wallin sits on 7.9, at or near its peak. The blue line is Wallin's projected Rating — 35.6 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.
