Watch points

  • Game time. Only 34.6% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 45.2, Ryun-Seong carries the 2nd-highest potential of the full-backs in the K League 1 of 15 — though on just 20 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.19 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
