K. Demirbay is a 33-year-old defensive midfielder at Eyüpspor, rated 18.4 overall by Field Insider's model, ranking 288th of 327 in the Süper Lig. A seasoned veteran, he has been a regular starter this season (78.3% of available minutes). His defensive output reads 3.87 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Demirbay.
Judged on this season alone, Demirbay graded 29 — a solid campaign that ranks top 39% of the 42 defensive midfielders in the Süper Lig, on 1 goal, 0 assists and 3.874 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 10 → 29). Over the 6 seasons on record his form has held fairly steady, peaking in 2021/22.
On long-term talent our Rating reads 18, 38th of 42 of the 42 defensive midfielders in the Süper Lig. At 33 Demirbay is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.5 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
3.87 tackles, blocks & interceptions per 90 — solid defensive volume, with 5 clean sheets across 27 appearances. Doing that for a lower-table side (15th of 18) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 18.4, Demirbay carries the 38th-highest potential of the defensive midfielders in the Süper Lig of 42, and he is posting that for a lower-table side (Eyüpspor finished 15th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as solid defensive volume (3.87 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~7), then tapers with age. At 33, Demirbay sits on 2.5, past its peak and easing. The blue line is Demirbay's projected Rating — 18.4 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
