1 clean sheet in 4 appearances (25% of games). Playing behind an upper-table side (5th of 20) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.

Watch points

  • Game time. Only 10.3% of available minutes — needs a settled run to prove the level.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 21.8 overall — below regular-starter level. A limited game time keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
