Editorial policy

This page explains how Previa 90 content is made and the rules we follow.

What we publish

Previews of the biggest Liga MX, Champions League, Copa Libertadores, Premier League, LaLiga and NFL matches, league tables and stats for every competition, and the results of matches already played in Past previews.

Where the data comes from

Results, tables, stats, squads, injuries and head-to-head records come from professional sports data providers. Late news (absences, possible line-ups and TV channels) is checked against reputable sports media, and we list the sources we used at the end of every preview.

How previews are written

Previews are written automatically with the help of artificial intelligence, under fixed rules: no results, injuries or figures are made up; if a detail is not confirmed, it is not published. We check that every player mentioned plays for that team today and remove any possible line-up that contains an error.

Our prediction

Every preview ends with our score prediction. It is a sporting opinion based on the match data, not a recommendation or a guarantee of anything.

Independence

No sponsor reviews, pays for or changes our analysis or predictions. Third-party advertising appears only on the Sponsors page and is always labelled as sponsored content.

When we publish

Each preview goes live about 33 hours before kick-off, in Spanish, English and Portuguese. Tables and stats are updated every day.

Corrections

If you spot a mistake, write to [email protected] with the page link. We review every report and fix errors as quickly as we can.
