There is no way to restart your account to start all over again. However you can visit your Academy and then your Youth Camp. You will be able to recruit a new player in your Pro Team and then start a whole new career with this player. Take note that you must reach a Coach Level of 9 before being able to manage a new player. (see "what does the Coach Level represent?")
How can I restart my progression?
