K. Tierney is a 29-year-old full-back at Celtic, rated 35.3 overall by Field Insider's model, ranking 134th of 226 in the Premiership. An experienced operator, he has been a regular starter this season (73.5% of available minutes). His defensive output reads 2.93 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Tierney.
Judged on this season alone, Tierney graded 36 — a strong campaign that ranks top 25% of the 41 full-backs in the Premiership, on 10 clean sheets and 2.934 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 5 → 36). Across the 6 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 35, 25th of 41 of the 41 full-backs in the Premiership. At 29 Tierney is in his prime years, and a market index of 7.2 reflects that trajectory.
A career still climbing — Tierney is at his peak right now, and the curve hasn't flattened.
2.93 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 35 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. Going forward he chipped in 6 goals and 8 assists — a useful bonus from the back.
With a Rating of 35.3, Tierney carries the 25th-highest potential of the full-backs in the Premiership of 41. Defensively he reads as moderate defensive volume (2.93 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).

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 (~13), then tapers with age. At 29, Tierney sits on 7.2, past its peak and easing. The blue line is Tierney's projected Rating — 35.3 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.
