Scout report

Squad depthGoalkeeper

J. Bursik is a 26-year-old goalkeeper at Portsmouth, rated 49.3 overall by Field Insider's model. In his prime years, he has been a fringe squad member this season (19.7% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Bursik.

On the season, Bursik graded 4 for current form (age-blind), on 2 clean sheets across 10 appearances.

Year-on-year, that's broadly in line with last season (Season 4 → 4). Over the 7 seasons on record his form has drifted down, peaking in 2021/22.

On long-term talent our Rating reads 49. At 26 Bursik is in his prime years, and a market index of 22.7 reflects that trajectory.

2 clean sheets in 10 appearances (20% of games). Keeping that many behind a lower-table side (18th of 24) — a side that concedes more — points to a busy, productive season between the posts.

Watch points

  • Game time. Only 19.7% of available minutes — needs a settled run to prove the level.

Outlook

Rated 49.3 overall — a solid contributor and squad regular. A limited game time keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
