Scout report

Squad depthCentral defender

C. Masterson is a 27-year-old central defender at Gillingham, rated 22.5 overall by Field Insider's model, ranking 79th of 134 on scout potential in the League Two. In his prime years, he has been a fringe squad member this season (18.5% of available minutes). His defensive output reads 2 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Masterson.

Judged on this season alone, Masterson graded 5 — a workmanlike campaign that ranks 33rd of 33 of the 33 centre-backs in the League Two, on 2 clean sheets and 2.003 defensive actions per 90.

Year-on-year, that's a drop on last season (Season 22 → 5). Over the 6 seasons on record his form has trended upward, peaking in 2023/24.

On long-term talent our Rating reads 23, 22nd of 33 of the 33 centre-backs in the League Two. At 27 Masterson is in his prime years, and a market index of 2.4 reflects that trajectory.

Clean sheets

2 tackles, blocks & interceptions per 90 — moderate defensive volume, with 2 clean sheets across 12 appearances. Doing that for a lower-table side (17th of 24) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 2 goals and 0 assists — a useful bonus from the back.

Strengths

  • Attacking threat. Chips in from deep: 0.24 goal involvements per 90, useful for a central defender.

Watch points

  • Game time. Only 18.5% 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 22.5, Masterson carries the 22nd-highest potential of the centre-backs in the League Two of 33 — though on just 12 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2 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.
