14 clean sheets in 37 appearances (38% of games). Playing behind an upper-table side (6th of 20) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.

Strengths

  • Availability. On the pitch for 97.4% of available minutes — a dependable presence in the XI.

Watch points

  • Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

Rated 56.3 overall — a solid contributor and squad regular. A near ever-present keeper carrying the gloves this season. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
