Clean sheets

2.25 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 21 appearances. Behind an upper-table side (4th of 15) 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.

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 (~6), then tapers with age. At 28, Vieira sits on 3.6, past its peak and easing. The blue line is Vieira's projected Rating — 31.8 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.
