First go to game options then go to edit mode. After go to player edit and then go to new player.

This option allows you to make your own player.

First choose his position, after choose his name, then chose what he looks like and change his nationality to the last flag, then chose his stats such as accuracy shot power etc and now go to stock.

Choose a space for him to go on. Now you wont be able to put him on a team because he will be only allowed to go on the master teams.

After all that start a new master league and go to the last screen (it will say edited). As you can see he will be worth 50 points.

I know it's hard to earn but when you do earn the points.

Buy him and he will be unstopable as long as you but all his stats up at the highest when you edited his stats at edit mode
