Leopold Querfeld

Across 2,704 published minutes for 1. FC Union Berlin in the Bundesliga, Leopold Querfeld currently profiles as an aerially active centre-back. Aerial-win output at 4.26 per 90 (96th percentile) is the role-defining signal, backed by clearance output at 7.36 per 90 (92nd percentile) and duel-win output at 7.02 per 90 (94th percentile). The event return catches the eye. Line management and his response without a compact block around him remain unmeasured.

Centre-Back

Completed long-pass volume at 4.49 per 90 is another plus in the 93rd percentile. Film still has to settle his positioning, recovery defending and choices when the line is exposed.

What to test on film

The published measures do not flag one obvious statistical concern.

Percentile flags open questions; they do not close them. Video, role, opponent quality and tactical context remain essential.

Comparable role shapes

Nearby public percentile profiles provide a starting point for comparison, not a claim of equal quality or upside.

Similar public profiles

Profile-shape index is a capped 0–100 similarity index built from distance across the same complete published role dimensions with identical constituent metric sets. It is not a probability and does not claim equal ability, potential, or tactical fit. The mean profile-percentile gap compares the average of those matched dimensions.

Profile context and privacyPublic identity fields, release dates and age-protection boundaries.

Position group: Defender
Position: CB

Ages are shown only in whole years. Exact birth dates are not published for any player. Under-18 profiles do not display portraits, physical details, or detailed history.

How to read this profileHigh-level onlyInterpretation guidance and limitations without publishing proprietary calculation weights.

Wonderkid Score

A position-aware discovery score informed by performance, age, playing time and competition context. It prioritizes search and comparison; it is not a career prediction.

Percentiles and scout prompts

Percentiles compare current published role evidence. Low involvement is not automatically a weakness; tactics, opponent quality, sample size and video context still matter.

Versioned release

This score is bound to release global-top-250-2026-07-18. A public “what moved” explanation will appear only after a second comparable score, minutes and role snapshot exists.

Youth age context

Verified private cohort windows can be retained as coarse validation bands. The current release does not apply a relative-age score correction. Exact birth dates are never published, and unavailable context is never inferred.

Detailed model weights, internal provider identifiers and raw source payloads are not part of the public profile. Unavailable athletic-tracking, off-ball, contract and event-location evidence is omitted rather than estimated.

Coverage gapsNot scoredImportant scouting dimensions reserved for verified evidence rather than inferred from conventional event totals.

Athletic tracking

Top speed, acceleration, repeat sprinting and contact tolerance require consistent tracking or testing data.

Off-ball intelligence

Movement, scanning, space creation and pressure behaviour require observed location data or reviewed video.

Scout projection

Ceiling, tactical fit and development priorities require a verified human scouting report and longitudinal evidence.

Spatial evidence

Action maps require verified player-linked event coordinates. Territory, off-ball movement and physical maps require tracking data and are never estimated from totals.

Evidence grade

How much reviewed public evidence supports this profile—not a talent grade.
