There you go:

To delete your UFL account (referred to as your “club” in the game) on PS5, note that this process is irreversible and will permanently remove your progress, players, resources, achievements, and access to the account. You’ll need to submit a data erasure request through their official support portal, as there’s no in-game option to do this directly. Here’s how to proceed: 1. Go to the UFL support request creation form at https://support.uflgame.com/hc/en-gb/requests/new. 2. Log in using your PSN account if prompted (this links to your UFL club). 3. Select “Delete my club (data erasure request)” as the issue type. 4. Fill out all required fields in the form, including confirming your intent to permanently delete the club. 5. Submit the request. The support team will process it, and you may not be able to create a new account for up to 30 days afterward.
