10 clean sheets in 33 appearances (30% of games). Keeping that many behind a relegation-threatened side (6th of 6) — a side that concedes more — points to a busy, productive season between the posts.

Strengths

  • Availability. On the pitch for 94.3% of available minutes — a dependable presence in the XI.

Watch points

  • Age curve. At 33, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 0.7, Koubek carries the 20th-highest potential of the goalkeepers in the Czech Liga of 26, and he is posting that for a relegation-threatened side (Slovan Liberec finished 6th of 6) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. A near ever-present keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).
