Output in context · FK Jablonec finished 5th of 6 · a relegation-threatened side
3.47 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 20 appearances. Doing that for a relegation-threatened side (5th of 6) 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. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
Strengths
- Availability. On the pitch for 89.4% of available minutes — a dependable presence in the XI.
Watch points
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 41.8, Sláma carries the 20th-highest potential of the centre-backs in the Czech Liga of 47, and he is posting that for a relegation-threatened side (FK Jablonec finished 5th of 6) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (3.47 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.
