All those changes are cosmetic - for the fun of the game and the pocket of nordeus haha.
Beyond the Myth :
I also change the names of my players, usually the 18 y.o. fast trainers, which I intend to keep in my team for 4-5 seasons.
Here is two things -
- one is that I train and improve a lot my player so he's getting better during time
- My player, with the new fancy name of a football star, now attract more my attention during the game (than before, with a weird name from a weird country ).
