Scout report

Experienced headGoalkeeper

W. Popp is a 31-year-old goalkeeper at Shonan Bellmare, rated 18.1 overall by Field Insider's model, ranking 307th of 377 on scout potential in the J1 League. A seasoned veteran, he has been a fringe squad member this season (18.4% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Popp.

Judged on this season alone, Popp graded 1 — a workmanlike campaign that ranks 29th of 31 of the 31 goalkeepers in the J1 League, on 1 clean sheet across 7 appearances.

Year-on-year, that's a drop on last season (Season 6 → 1). Over the 3 seasons on record his form has drifted down, peaking in 2024/25.

On long-term talent our Rating reads 18, 20th of 31 of the 31 goalkeepers in the J1 League. At 31 Popp is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.2 reflects that trajectory.

1 clean sheet in 7 appearances (14% of games). Keeping that many behind a relegation-threatened side (19th of 20) — a side that concedes more — points to a busy, productive season between the posts.

Watch points

  • Game time. Only 18.4% of available minutes — needs a settled run to prove the level.
  • Age curve. At 31, 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 18.1, Popp carries the 20th-highest potential of the goalkeepers in the J1 League of 31 — though on just 7 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
