Below: strengths, watch-points, market-value outlook and the latest transfer news on Foss.

Year-on-year, that's a clear step up on last season (Season 3 → 15). Over the 6 seasons on record his form has drifted down, peaking in 2023/24.
On long-term talent our Rating reads 26, 27th of 43 of the 43 centre-backs in the 1. Division. At 27 Foss is in his prime years, and a market index of 8.2 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
1.63 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 10 appearances. Behind a title-challenging side (1st of 16) 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. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 25.5, Foss carries the 27th-highest potential of the centre-backs in the 1. Division of 43 — though on just 10 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.63 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
Generated from Field Insider's rating model · AI-written analysis to follow.
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 (~8), then tapers with age. At 27, Foss sits on 8.2, at or near its peak. The blue line is Foss's projected Rating — 25.5 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.
