so i am fairly new to FM and i have been looking online to find some wonderkids/must have players and a lot of the players i can't find when i search for them, is there a way to add more players into my game?
The players will only show up if you have loaded the leagues they play in when starting a new game. For example if a player plays for a team in Russia, and you did not load the Russian leagues when starting the game, it is likely that the player will not show up when you search for him.
EDIT: You can add/load leagues during the game without having to start a new save game. Go to FM>Add/Remove Leagues. However this will only take effect when the new season starts in the game.
There are also certain add ins on various FM websites which allow you to add a specific file of wonderkids into the game. You can search for it and it should come up if you want to add only wonderkids in particular to your game.
