Free-to-play transfers

You can edit your team and change your lineup at any time during the gameweek, by clicking on your team, and then on the "Edit" button. You'll be redirected towards the onboarding page of the competition to transfer a player for another one if wanted.

You can substitute any player but it has to be done before he starts playing in his real-life game. After that he'll be locked until the end of the gameweek competition, so you'll have to wait until Monday to transfer him for the gameweek after.
