S. Doi is a 34-year-old central midfielder at Montedio Yamagata, rated 11.1 overall by Field Insider's model, ranking 831st of 874 in the J3 League. A seasoned veteran, he has been a fringe squad member this season (25.8% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Doi.
Judged on this season alone, Doi graded 6 — a workmanlike campaign that ranks 160th of 241 of the 241 central midfielders in the J3 League, on 2 goals, 0 assists and 0 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 3 → 6). Over the 6 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 11, 235th of 241 of the 241 central midfielders in the J3 League. At 34 Doi is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.5 reflects that trajectory.
Below his 2020/21 peak but holding a solid level — the platform for a return is there.
0 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 13 appearances. Going forward he chipped in 2 goals and 0 assists — a useful bonus from the back.
With a Rating of 11.1, Doi carries the 235th-highest potential of the central midfielders in the J3 League of 241 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).
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 (~8), then tapers with age. At 34, Doi sits on 2.5, past its peak and easing. The blue line is Doi's projected Rating — 11.1 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.
