On long-term talent our Rating reads 31, 19th of 39 of the 39 full-backs in the Greece tier 1. At 27 Onyemaechi is in his prime years, and a market index of 13.6 reflects that trajectory.
A career still climbing — Onyemaechi is at his peak right now, and the curve hasn't flattened.
4.08 tackles, blocks & interceptions per 90 — solid defensive volume, with 8 clean sheets across 17 appearances. Behind a title-challenging side (2nd of 14) 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.
With a Rating of 31, Onyemaechi carries the 19th-highest potential of the full-backs in the Greece tier 1 of 39. Defensively he reads as solid defensive volume (4.08 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.

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 (~14), then tapers with age. At 27, Onyemaechi sits on 13.6, at or near its peak. The blue line is Onyemaechi's projected Rating — 31 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.
