Clean sheets

0.94 tackles, blocks & interceptions per 90 — light defensive volume, with 9 clean sheets across 28 appearances. Behind a title-challenging side (2nd of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 2 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.18 goal involvements per 90, useful for a central midfielder.

Watch points

  • Game time. Only 44.9% of available minutes — needs a settled run to prove the level.
  • Defensive numbers. Modest 0.94 defensive actions per 90 for the position.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 42.1, Masa carries the 16th-highest potential of the central midfielders in the J1 League (top 25%). Defensively he reads as light defensive volume (0.94 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
