Scout report
M. Heyer is a 31-year-old full-back at Fortuna Düsseldorf, rated 23.4 overall by Field Insider's model. A seasoned veteran, he has been a fringe squad member this season (32.4% of available minutes). His defensive output reads 3.54 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Heyer.
On the season, Heyer graded 11 for current form (age-blind), on 2 clean sheets and 3.542 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 32 → 11). Over the 6 seasons on record his form has drifted down, peaking in 2021/22.
On long-term talent our Rating reads 23. At 31 Heyer is into the veteran stage, where the age curve weighs on the projection, and a market index of 4 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
Output in context · Fortuna Düsseldorf finished 17th of 18 · a relegation-threatened side
3.54 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 19 appearances. Doing that for a relegation-threatened side (17th 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.
Strengths
- Defensive volume. 3.54 tackles, blocks & interceptions per 90 — does the unseen work.
Watch points
- Game time. Only 32.4% of available minutes — needs a settled run to prove the level.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 23.4 overall — below regular-starter level. Defensively he reads as solid defensive volume (3.54 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
