Clean sheets

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.

Strengths

  • Availability. On the pitch for 73.5% of available minutes — a dependable presence in the XI.
  • Attacking threat. Chips in from deep: 0.5 goal involvements per 90, useful for a full-back.

Watch points

  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

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).
