Dion-Johan Cools is a 30-year-old full-back at Cerezo Osaka, rated 24.2 overall by Field Insider's model, ranking 656th of 874 in the J3 League. An experienced operator, he has been a fringe squad member this season (27% of available minutes). His defensive output reads 4 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Cools.
Judged on this season alone, Cools graded 8 — a workmanlike campaign that ranks 73rd of 79 of the 79 full-backs in the J3 League, on 1 clean sheet and 3.998 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 10 → 8). Over the 3 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 24, 60th of 79 of the 79 full-backs in the J3 League. At 30 Cools is into the veteran stage, where the age curve weighs on the projection, and a market index of 9.2 reflects that trajectory.
Past his 2020/21 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
4 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 14 appearances. Going forward he chipped in 2 goals and 1 assist — a useful bonus from the back.
With a Rating of 24.2, Cools carries the 60th-highest potential of the full-backs in the J3 League of 79 — though on just 14 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 30, Cools sits on 9.2, past its peak and easing. The blue line is Cools's projected Rating — 24.2 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.
