Clean sheets

2.36 tackles, blocks & interceptions per 90 — moderate defensive volume, with 8 clean sheets across 19 appearances. Behind a title-challenging side (1st 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 0 goals and 4 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.22 goal involvements per 90, useful for a full-back.

Watch points

  • Game time. Only 49% 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 26.2, Anzai carries the 4th-highest potential of the full-backs in the J1 League of 7. Defensively he reads as moderate defensive volume (2.36 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
