6 clean sheets in 24 appearances (25% of games). Playing behind an upper-table side (6th of 18) means a more protected goal, so the read is about command and distribution as much as raw shut-outs.

Strengths

Availability. On the pitch for 69.6% of available minutes — a dependable presence in the XI.
Pedigree. Performing in a top-tier setting (team strength 88.3/100).

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

Rated 29.3 overall — below regular-starter level. A a regular starter keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.7× and falling).

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 (~18), then tapers with age. At 33, Flekken sits on 6.1, past its peak and easing. The blue line is Flekken's projected Rating — 29.3 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.
