J. Blaswich is a 35-year-old goalkeeper at Bayer Leverkusen, rated 17.3 overall by Field Insider's model, ranking 324th of 325 in the Bundesliga. A seasoned veteran, he has been a fringe squad member this season (31.3% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Blaswich.
Judged on this season alone, Blaswich graded 5 — a workmanlike campaign that ranks 18th of 23 of the 23 goalkeepers in the Bundesliga, on 2 clean sheets across 11 appearances.
Year-on-year, that's a drop on last season (Season 20 → 5). Over the 5 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 17, 23rd of 23 of the 23 goalkeepers in the Bundesliga. At 35 Blaswich is into the veteran stage, where the age curve weighs on the projection, and a market index of 8.6 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2 clean sheets in 11 appearances (18% 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.
With a Rating of 17.3, Blaswich carries the 23rd-highest potential of the goalkeepers in the Bundesliga of 23 — though on just 11 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).

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 (~29), then tapers with age. At 35, Blaswich sits on 8.6, past its peak and easing. The blue line is Blaswich's projected Rating — 17.3 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.
