Clean sheets

3.46 tackles, blocks & interceptions per 90 — moderate defensive volume, with 9 clean sheets across 34 appearances. Behind a title-challenging side (2nd of 24) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 3 goals and 3 assists — a useful bonus from the back.

Strengths

Attacking threat. Chips in from deep: 0.22 goal involvements per 90, useful for a central defender.

Outlook

Rated 25.6 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.46 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

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 28, Mellish sits on 2.8, past its peak and easing. The blue line is Mellish's projected Rating — 25.6 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.
