S. Diomandé is a 25-year-old central defender at Auxerre, rated 73.9 overall by Field Insider's model, ranking 110th of 337 in the Ligue 1. In his prime years, he has been an ever-present this season (87.8% of available minutes). His defensive output reads 3.29 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Diomandé.
Judged on this season alone, Diomandé graded 40 — a solid campaign that ranks top 34% of the 54 centre-backs in the Ligue 1, on 6 clean sheets and 3.29 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 64 → 40). Over the 6 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 74, top 30% of the 54 centre-backs in the Ligue 1. At 25 Diomandé is in his prime years, and a market index of 43.1 reflects that trajectory.
Read the appearance count in context: Diomandé missed 5 games through injury and 2 suspensions (thigh, injured) out of roughly 34 this season. The 24 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
3.29 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 24 appearances. Doing that for a lower-table side (15th of 18) 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 2 assists — a useful bonus from the back.
With a Rating of 73.9, Diomandé carries the 16th-highest potential of the centre-backs in the Ligue 1 (top 30%), and he is posting that for a lower-table side (Auxerre finished 15th of 18) — 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 moderate defensive volume (3.29 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. Doing it for a lesser side, he profiles as a value buy for a club higher up the table.

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 (~43), then tapers with age. At 25, Diomandé sits on 43.1, at or near its peak. The blue line is Diomandé's projected Rating — 73.9 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.
