The Master league has three divisions. When starteing you choose your team but start with default Master league players that suck pretty good. There are 3 divisions 3 being the lowest and starting point. The object is to gain money (by winning games) buy better players, and move up into the top league. It puts you in the place of the coach and the manager. It is what I play the most on Winning Eleven 6 (the original jap version) and is the best long term aspect of the game.
