On long-term talent our Rating reads 28, 55th of 70 of the 70 full-backs in the Serie A. At 33 Alonso is into the veteran stage, where the age curve weighs on the projection, and a market index of 13.1 reflects that trajectory.
Below his 2020/21 peak but holding a solid level — the platform for a return is there.
2.58 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 31 appearances. Going forward he chipped in 1 goal and 1 assist — a useful bonus from the back.
With a Rating of 28.4, Alonso carries the 55th-highest potential of the full-backs in the Serie A of 70. Defensively he reads as moderate defensive volume (2.58 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).

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 (~38), then tapers with age. At 33, Alonso sits on 13.1, past its peak and easing. The blue line is Alonso's projected Rating — 28.4 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.
