There are two ways to get this trophy.
First, start a manager mode, play an entire season (including friendlies) without simming a single game. This is not challenging, however, it takes quite a long time.
The second, and much easier method is to start a new manager mode. Start EVERY game, but as soon the game has started (kick off), just press start and forfeit the match. By the end of November you will be notified that your performance at the club will be reviewed (typically you will have to "play" one more game) and after that you will receive another email saying you have been fired due to poor performance.
Once you receive that email, you will be redirected to the "career/team selection screen" where you will be asked to choose a new team to continue your poor manager career. At this screen you will receive the trophy.
*This takes about 20-30 minutes
*Important note: Do NOT select "Player Manager Mode" it needs to be done in the regular "Manager Mode"
