Easily Improve Created Players
Make a new player and disable the auto-save feature. Once you reach Junior level you will start getting 50, 70, or 100 experience points per match. You can gain the points of two or three tournaments and then spend them in the player area. When you finish improving the desired areas, save the player improvements then exit Career mode without saving your career progress. When you play Career mode again, the tournaments will be able to played again and you can gain more points.
