Clean sheets

3.8 tackles, blocks & interceptions per 90 — solid defensive volume, with 7 clean sheets across 39 appearances. Doing that for a relegation-threatened side (24th 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. Going forward he chipped in 2 goals and 4 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 70.9% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.18 goal involvements per 90, useful for a full-back.
Defensive volume. 3.8 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 41.6 overall — developing / rotation level. Defensively he reads as solid defensive volume (3.8 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.

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 (~10), then tapers with age. At 26, Guinness-Walker sits on 9.9, at or near its peak. The blue line is Guinness-Walker's projected Rating — 41.6 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.
