Year-on-year, that's a drop on last season (Season 8 → 1). Over the 4 seasons on record his form has drifted down, peaking in 2020/21.

On long-term talent our Rating reads 3. At 37 Köybaşı is into the veteran stage, where the age curve weighs on the projection, and a market index of 0.1 reflects that trajectory.

Clean sheets

3.46 tackles, blocks & interceptions per 90 — moderate defensive volume across 9 appearances. Behind an upper-table side (6th of 18) 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.

Watch points

  • Game time. Only 3.6% of available minutes — needs a settled run to prove the level.
  • Age curve. At 37, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 2.6 overall — below regular-starter level. Defensively he reads as moderate defensive volume (3.46 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.5× and falling).
