Outlook

With a Rating of 15.6, Buen carries the 5th-highest potential of the full-backs in the Liga MX of 5 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.7 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

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 (~5), then tapers with age. At 35, Buen sits on 1.6, past its peak and easing. The blue line is Buen's projected Rating — 15.6 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.
