A couple of months after this has been implemented I am coming back on this. I don't understand at all what the advantages/disadvantages are of only showing a limited number of starplayers in the players list. If you click on it you can see the star.
I prefer to go back to the old display, also like the 1-3 stars (silver, gold or combination) display a lot more.
When looking at the player individually, he may seem to be a star, while the team list show only the biggest stars (depending on club level). It's the same thing but much more meaningful.
Before it showed all stars now the team list shows the biggest stars. It's more attractive than displaying a list with 20+ stars.
It's a design thing really. The stars are still stars, the merchandise still generates the money..
