Im tryingto swap one of my players and replacing him with a player from the same club but it says i cant cos i would have more than 3 but its a straight replacement
Sorry about this, it's on my list of fixes, i'll get onto it asap. In the meantime you'll have to swap him for another player of another team then reselect the player you want. You will use a change in doing this, so it's up to you.
