Clean sheets

1.83 tackles, blocks & interceptions per 90 — light defensive volume across 26 appearances. Doing that for a relegation-threatened side (14th of 16) 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 1 goal and 0 assists — a useful bonus from the back.

Watch points

Game time. Only 45.6% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 1.83 defensive actions per 90 for the position.
Age curve. At 31, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

Rated 10.2 overall — below regular-starter level. Defensively he reads as light defensive volume (1.83 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× 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 22–27 (~1), then tapers with age. At 31, Tsonkov sits on 0.3, past its peak and easing. The blue line is Tsonkov's projected Rating — 10.2 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.
