A. Ralston is a 27-year-old central defender at Celtic, rated 35.1 overall by Field Insider's model, ranking 39th of 69 on scout potential in the Premiership. In his prime years, he has been a rotation option this season (38% of available minutes). His defensive output reads 3.39 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Ralston.
Judged on this season alone, Ralston graded 19 — a workmanlike campaign that ranks 13th of 19 of the 19 centre-backs in the Premiership, on 5 clean sheets and 3.392 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 19 → 19). Over the 6 seasons on record his form has trended upward, peaking in 2021/22.
On long-term talent our Rating reads 35, 10th of 19 of the 19 centre-backs in the Premiership. At 27 Ralston is in his prime years, and a market index of 7.8 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
Output in context · Celtic finished 3rd of 12 · an upper-table side
3.39 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 24 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.
Watch points
- Game time. Only 38% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 35.1, Ralston carries the 10th-highest potential of the centre-backs in the Premiership of 19. Defensively he reads as moderate defensive volume (3.39 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.
