We hold a single season for Diaby, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 33, 28th of 46 of the 46 full-backs in the Super League. At 26 Diaby is in his prime years, and a market index of 17.9 reflects that trajectory.
4.38 tackles, blocks & interceptions per 90 — solid defensive volume across 22 appearances. Doing that for a relegation-threatened side (12th of 12) 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 1 goal and 1 assist — a useful bonus from the back.
With a Rating of 33.1, Diaby carries the 28th-highest potential of the full-backs in the Super League of 46, and he is posting that for a relegation-threatened side (FC Winterthur finished 12th of 12) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as solid defensive volume (4.38 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.

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 (~18), then tapers with age. At 26, Diaby sits on 17.9, at or near its peak. The blue line is Diaby's projected Rating — 33.1 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.
