The principle
Data should narrow the search—not make the final decision.
A Wyscout export can contain hundreds of players and dozens of metrics. The useful work is not finding the player with the biggest number. It is defining the right peer group, choosing metrics that reflect the role and using the results to decide who deserves deeper review.
Start with the recruitment question
Write the brief before opening the data. A useful brief describes the role, competition level, age window, expected playing time, financial constraints and the actions the player must perform. “We need a midfielder” is too broad. “We need a press-resistant number six who can progress possession and defend transitions” creates a testable question.
Translate the brief into observable traits
Separate essential traits from supporting traits. For a progressive midfielder, essential evidence might include progressive passes, passes into the final third, passing accuracy under an appropriate volume and ball retention. Defensive actions, interceptions and duel success may support the picture. The exact combination depends on the team’s game model.
Choose the role first and the metrics second. Choosing impressive-looking metrics first creates confirmation bias.
Build the Wyscout export
Run a Wyscout player search for the relevant season and competitions. Export the result as an XLSX or CSV file. Include player name and minutes played as a minimum, plus position, age, club and the performance metrics linked to the brief.
Use a broad first export
It is often useful to include every plausible position and then create narrower cohorts during analysis. This keeps the original dataset intact and lets you test how conclusions change when the comparison group changes.
- Use one consistent time period.
- Include minutes so low-sample players can be filtered.
- Prefer per-90 and percentage metrics when comparing opportunity-dependent actions.
- Keep raw contextual fields such as age, team and market value.
- Do not remove inconvenient metrics before examining the profile.
Create a fair comparison cohort
A percentile only describes a player relative to the other players in the selected group. Change the cohort and the percentile changes. That makes cohort design one of the most important analytical decisions.
Set a threshold that reduces tiny samples without excluding legitimate emerging players.
Compare players performing sufficiently similar roles. Full backs and centre backs should rarely share one core profile.
Use the real recruitment window, but remember that age is a constraint rather than a performance metric.
League strength and team dominance affect opportunities and outputs. Treat cross-league results as screening evidence.
Test the stability of the result
Run the analysis with more than one sensible cohort. If a player remains strong when the minutes threshold or age window changes, the signal is more stable. If the conclusion disappears immediately, investigate why.
Interpret percentiles correctly
An 80th-percentile result means the player’s raw value is equal to or higher than 80% of valid players in that active cohort. It does not mean the player is 80% “good”, nor does it automatically mean the underlying action helps the team.
Read raw values beside ranks
Percentiles make differently scaled metrics easier to compare, while raw values show the size of the underlying difference. Two players can sit in adjacent percentile bands even when their raw values are almost identical. Always examine both.
Use radar charts as summaries
A radar is useful for recognising profile shape, not for calculating overall quality. Check the axes, cohort and raw numbers before drawing a conclusion. A large shape can still reflect the wrong role or an unbalanced metric selection.
Team possession, tactical responsibility, game state, competition quality and set-piece duties can all affect a player’s statistical profile.
Move from data to shortlist
Use the data to create a review order. Start with players who meet the essential parts of the brief, then record why each player is interesting and what still needs to be tested.
- Screen: remove players outside the genuine constraints.
- Profile: compare role-relevant metrics and identify outliers.
- Challenge: look for weaknesses, missing data and alternative explanations.
- Compare: place credible candidates side by side using the same cohort.
- Validate: review video, tactical role, physical qualities and decision-making.
- Document: save the evidence, risks and next action in a concise report.
Talent DNA can perform the cohort filtering, percentile calculation, profile comparison and PDF reporting locally in your browser. The resulting report should support the scouting process, not replace it.

Ranking incompatible roles together
A high number may reflect role and opportunity rather than superior execution.
Ignoring playing time
Small samples create volatile per-90 numbers and misleading extremes.
Treating every metric as equally valuable
Metric importance must come from the recruitment brief and game model.
Using one composite score as the verdict
A rating is a screening summary. It cannot capture tactical fit, behaviour, availability or future development.
Skipping counter-evidence
Actively search for reasons the attractive profile may not translate.
Stopping before video
Data identifies what to investigate. Video and live observation explain how and why it happens.
