J. Bos is a 23-year-old full-back at Feyenoord, rated 76.9 overall by Field Insider's model, ranking 17th of 299 in the Eredivisie. An emerging talent, he has been a regular starter this season (71.5% of available minutes). His defensive output reads 4.24 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Bos.
Judged on this season alone, Bos graded 42 — an excellent campaign that ranks top 8% of the 51 full-backs in the Eredivisie, on 7 clean sheets and 4.242 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 9 → 42). Across the 3 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 77, top 6% of the 51 full-backs in the Eredivisie. At 23 Bos is still climbing toward his ceiling, and a market index of 98.4 reflects that trajectory.
A career still climbing — Bos is at his peak right now, and the curve hasn't flattened.
4.24 tackles, blocks & interceptions per 90 — solid defensive volume, with 7 clean sheets across 28 appearances. Behind a title-challenging side (2nd of 18) 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 4 goals and 7 assists — a useful bonus from the back.
With a Rating of 76.9, Bos carries the 3rd-highest potential of the full-backs in the Eredivisie (top 6%). Defensively he reads as solid defensive volume (4.24 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead. With this floor already at 23, the ceiling gets tested by a step up in level — one to track.
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 (~98), then tapers with age. At 23, Bos sits on 98.4, at or near its peak. The blue line is Bos's projected Rating — 76.9 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.
