Clean sheets

3.63 tackles, blocks & interceptions per 90 — solid defensive volume, with 4 clean sheets across 34 appearances. Doing that for a lower-table side (14th of 20) 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.

Strengths

Availability. On the pitch for 87.7% of available minutes — a dependable presence in the XI.
Defensive volume. 3.63 tackles, blocks & interceptions per 90 — does the unseen work.
Pedigree. Performing in a top-tier setting (team strength 89.4/100).

Watch points

Age curve. At 32, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 39.5 overall — developing / rotation level. Defensively he reads as solid defensive volume (3.63 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.8× and falling).

Market valueRating

Solid = now · dashed = projected

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 (~32), then tapers with age. At 32, Jonny sits on 12.9, past its peak and easing. The blue line is Jonny's projected Rating — 39.5 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.
