Legendary players in game shop (PS4)

Hi all
could anyone explain me how to obtain legendary players from in-game shop? I see the list of them, there is price 'Free' for everyone of them but there is no way to buy any of them... Is that bug? Or maybe I do something wrongly.... I'll be really thankful for help.

Welcome to Focus world. They have the right (apparently?) to delist their games to promote the next ones.

(game is still available on PC)
