Clean sheets

4.02 tackles, blocks & interceptions per 90 — solid defensive volume, with 1 clean sheet across 5 appearances. Doing that for a lower-table side (14th of 18) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight.

Strengths

Defensive volume. 4.02 tackles, blocks & interceptions per 90 — does the unseen work.
Ceiling. High potential at just 17 — room to grow into a bigger role.

Watch points

Game time. Only 29.3% of available minutes — needs a settled run to prove the level.

Outlook

Rated 75.864 overall — elite — among the best in the position. Defensively he reads as solid defensive volume (4.02 tackles, blocks & interceptions per 90). At 17 the trajectory points up — potential sits near its ceiling (100/100) and market value should climb as minutes and output follow. With this floor already at 17, the ceiling gets tested by a step up in level — one to track.

Market valueRating

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 (~44), then tapers with age. At 17, Tsiendi sits on 31, still climbing toward its peak. The blue line is Tsiendi's projected Rating — 75.864 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.
