On long-term talent our Rating reads 53, 30th of 55 of the 55 centre-backs in the Primeira Liga. At 26 Rivas is in his prime years, and a market index of 56 reflects that trajectory.
Read the appearance count in context: Rivas missed 3 games through injury (injured) out of roughly 34 this season. The 18 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 2023/24 peak but holding a solid level — the platform for a return is there.
3.21 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 18 appearances. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 52.8, Rivas carries the 30th-highest potential of the centre-backs in the Primeira Liga of 55. Defensively he reads as moderate defensive volume (3.21 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 (~56), then tapers with age. At 26, Rivas sits on 56, at or near its peak. The blue line is Rivas's projected Rating — 52.8 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.
