But if you give them a decent CA, probs around 110-130 and a large pa, 170+ and then give them similar attributes to the player you want them to be touted as the next then it may work.
when you create your player contract him to the club you want and give him the amount if money. also with the contract make sure you say it expires at least one year after it has started. then just to make sure in the search bar type in the club you have choose, double click when the search has done then go to staff and players. then there is a tab that says players click that and look for your created player.
