On long-term talent our Rating reads 36. At 25 Wallin is in his prime years, and a market index of 22.1 reflects that trajectory.
A career still climbing — Wallin is at his peak right now, and the curve hasn't flattened.
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.
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.

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 25, Wallin sits on 22.1, 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.
