Clean sheets

Strengths

  • Availability. On the pitch for 65.8% of available minutes — a dependable presence in the XI.
  • Defensive volume. 3.56 tackles, blocks & interceptions per 90 — does the unseen work.
  • Pedigree. Performing in a top-tier setting (team strength 91.4/100).
  • Ceiling. High potential at just 20 — room to grow into a bigger role.

Watch points

  • Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

With a Rating of 82.3, Martín carries the 4th-highest potential of the full-backs in the La Liga (top 16%). Defensively he reads as solid defensive volume (3.56 tackles, blocks & interceptions per 90). At 20 the trajectory points up — potential sits near its ceiling (98/100) and market value should climb as minutes and output follow. With this floor already at 20, the ceiling gets tested by a step up in level — one to track.
