To get custom teams into your game, you typically follow these steps:

eFootball PES 2021 - Team Raja Casablanca (Rjaa): A Tactical Guide and Overview

: Through community Option Files, players routinely patch real team names, kits, and current rosters into the engine.

If you somehow raise €5 million, do not buy a 74-rated striker. He will ruin your wage structure and cause morale drops in the original squad. Instead, buy two 68-rated loanees with "team player" role.

The PES 2021 simulation engine hates low-rated teams. If you simulate away to a top-half club, you will lose 4-0 every time. Play every single match. Master the "stun shot" from outside the box—it’s your only goal-scoring hope.

In the PES modding community, "Team Rjaa" or "Rjaa" is also the name of a group/individual who provides high-quality repacks and bypasses (cracks) for PES 2021.
