Clean sheets

3.54 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 8 appearances. Doing that for a lower-table side (15th 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.

Strengths

Defensive volume. 3.54 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Game time. Only 14.9% of available minutes — needs a settled run to prove the level.
Age curve. At 31, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 18 overall — below regular-starter level. Defensively he reads as solid defensive volume (3.54 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).

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 (~5), then tapers with age. At 31, Walsh sits on 2.2, past its peak and easing. The blue line is Walsh's projected Rating — 18 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.
