Outlook
With a Rating of 51.3, Doi carries the 2nd-highest potential of the centre-backs in the J1 League (top 4%). Defensively he reads as moderate defensive volume (2.68 tackles, blocks & interceptions per 90). At 21 the trajectory points up — potential sits near its ceiling (97/100) and market value should climb as minutes and output follow. With this floor already at 21, the ceiling gets tested by a step up in level — one to track.
