Scout report
J. Altena is a 22-year-old full-back at Heart Of Midlothian, rated 49.5 overall by Field Insider's model, ranking 18th of 104 on scout potential in the Premiership and 537th of 1748 U-23 players tracked. An emerging talent, he has been a regular starter this season (68% of available minutes). His defensive output reads 3.08 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Altena.
Judged on this season alone, Altena graded 26 — a workmanlike campaign that ranks 10th of 19 of the 19 full-backs in the Premiership, on 2 clean sheets and 3.076 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 33 → 26). Over the 3 seasons on record his form has trended upward, peaking in 2025/26.
On long-term talent our Rating reads 50, top 27% of the 19 full-backs in the Premiership. At 22 Altena is still climbing toward his ceiling, and a market index of 10.5 reflects that trajectory.
Past his 2025/26 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · Heart Of Midlothian finished 3rd of 12 · an upper-table side
3.08 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 8 appearances. Behind an upper-table side (3rd of 12) 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.
Strengths
- Availability. On the pitch for 68% of available minutes — a dependable presence in the XI.
Watch points
- Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.
Outlook
With a Rating of 49.5, Altena carries the 5th-highest potential of the full-backs in the Premiership of 19 — though on just 8 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (3.08 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead. With this floor already at 22, the ceiling gets tested by a step up in level — one to track.
