Marcos Alonso is a 35-year-old full-back at Celta Vigo, rated 33.7 overall by Field Insider's model, ranking 330th of 389 in the La Liga. A seasoned veteran, he has been an ever-present this season (96.2% of available minutes). His defensive output reads 2.83 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Alonso.
Judged on this season alone, Alonso graded 39 — a strong campaign that ranks top 24% of the 65 full-backs in the La Liga, on 8 clean sheets and 2.827 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 26 → 39). Over the 6 seasons on record his form has trended upward, peaking in 2021/22.
On long-term talent our Rating reads 34, 53rd of 65 of the 65 full-backs in the La Liga. At 35 Alonso is into the veteran stage, where the age curve weighs on the projection, and a market index of 18.6 reflects that trajectory.
Read the appearance count in context: Alonso missed 6 games through injury (jumpers knee, knee, injury) out of roughly 38 this season. The 32 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
2.83 tackles, blocks & interceptions per 90 — moderate defensive volume, with 8 clean sheets across 32 appearances. Behind an upper-table side (6th of 20) 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. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 33.7, Alonso carries the 53rd-highest potential of the full-backs in the La Liga of 65. Defensively he reads as moderate defensive volume (2.83 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× 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 (~62), then tapers with age. At 35, Alonso sits on 18.6, past its peak and easing. The blue line is Alonso's projected Rating — 33.7 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.
