Watch points

Game time. Only 53.9% of available minutes — needs a settled run to prove the level.
Defensive numbers. Modest 0.75 defensive actions per 90 for the position.
Age curve. At 36, both level and resale value are on the downslope.
Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 10.1, Delev carries the 39th-highest potential of the attacking midfielders in the First League of 44, and he is posting that for a lower-table side (Lokomotiv Sofia finished 11th of 16) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. In the final third he profiles as a productive contributor (0.5 goal contributions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

Value & potential by age

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 (~2), then tapers with age. At 36, Delev sits on 0.6, past its peak and easing. The blue line is Delev's projected Rating — 10.1 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.
