Year-on-year, that's a clear step up on last season (Season 68 → 75). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 44, 37th of 50 of the 50 full-backs in the Belgium tier 1. At 28 Allister is in his prime years, and a market index of 23.4 reflects that trajectory.
A career still climbing — Allister is at his peak right now, and the curve hasn't flattened.
5.36 tackles, blocks & interceptions per 90 — high defensive volume, with 16 clean sheets across 34 appearances. Behind a title-challenging side (2nd of 6) 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 1 goal and 1 assist — a useful bonus from the back.
With a Rating of 44.3, Allister carries the 37th-highest potential of the full-backs in the Belgium tier 1 of 50. Defensively he reads as high defensive volume (5.36 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).
Generated from Field Insider's rating model · AI-written analysis to follow.
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 (~39), then tapers with age. At 28, Allister sits on 23.4, past its peak and easing. The blue line is Allister's projected Rating — 44.3 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.
