R. Koeman is a 31-year-old goalkeeper at Telstar, rated 38.5 overall by Field Insider's model, ranking 247th of 299 in the Eredivisie. A seasoned veteran, he has been an ever-present this season (96.7% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Koeman.
Judged on this season alone, Koeman graded 8 — a workmanlike campaign that ranks 16th of 23 of the 23 goalkeepers in the Eredivisie, on 5 clean sheets across 33 appearances.
Year-on-year, that's a drop on last season (Season 46 → 8). Over the 5 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 39, 17th of 23 of the 23 goalkeepers in the Eredivisie. At 31 Koeman is into the veteran stage, where the age curve weighs on the projection, and a market index of 22.2 reflects that trajectory.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
5 clean sheets in 33 appearances (15% of games). Keeping that many behind a lower-table side (14th of 18) — a side that concedes more — points to a busy, productive season between the posts.
With a Rating of 38.5, Koeman carries the 17th-highest potential of the goalkeepers in the Eredivisie of 23, and he is posting that for a lower-table side (Telstar finished 14th of 18) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. A near ever-present keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× 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 (~49), then tapers with age. At 31, Koeman sits on 22.2, past its peak and easing. The blue line is Koeman's projected Rating — 38.5 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.
