Scout report
S. Doi is a 34-year-old central midfielder at Montedio Yamagata, rated 8.9 overall by Field Insider's model, ranking 214th of 226 on scout potential in the J2 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 7 — a solid campaign that ranks top 39% of the 70 central midfielders in the J2 League, on 2 goals, 0 assists and 0 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 2 → 7). Over the 6 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 9, 69th of 70 of the 70 central midfielders in the J2 League. At 34 Doi is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.6 reflects that trajectory.
Below his 2020/21 peak but holding a solid level — the platform for a return is there.
Output in context · Montedio Yamagata finished 10th of 20 · a mid-table side
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.
Strengths
- Attacking threat. Chips in from deep: 0.2 goal involvements per 90, useful for a central midfielder.
Watch points
- Game time. Only 25.8% of available minutes — needs a settled run to prove the level.
- Age curve. At 34, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 8.9, Doi carries the 69th-highest potential of the central midfielders in the J2 League of 70 — 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).
