Scout report
F. Kastenmeier is a 29-year-old goalkeeper at Fortuna Düsseldorf, rated 42.5 overall by Field Insider's model. An experienced operator, he has been an ever-present this season (94.1% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Kastenmeier.
On the season, Kastenmeier graded 8 for current form (age-blind), on 5 clean sheets across 32 appearances.
Year-on-year, that's a drop on last season (Season 23 → 8). Over the 6 seasons on record his form has drifted down, peaking in 2020/21.
On long-term talent our Rating reads 43. At 29 Kastenmeier is in his prime years, and a market index of 8.9 reflects that trajectory.
Past his 2020/21 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · Fortuna Düsseldorf finished 17th of 18 · a relegation-threatened side
5 clean sheets in 32 appearances (16% of games). Keeping that many behind a relegation-threatened side (17th of 18) — a side that concedes more — points to a busy, productive season between the posts.
Strengths
- Availability. On the pitch for 94.1% of available minutes — a dependable presence in the XI.
Watch points
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 42.5 overall — developing / rotation level. A near ever-present keeper carrying the gloves this season. Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
