MOVING A CLUB BETWEEN NATIONS[]
You can choose to move a club you own from one nation to another. The move happens at the end of the season, not during the season.
You cannot have more than one club in a single nation.
If you want to move a club to a nation where you already have a club then you must move the club already in that nation to another nation. When you do this you will need to move them one at a time. For example, if you want to move Club A to Club B's nation, then you would first have to move Club B to another nation, and then move Club A to Club B's old nation.
If you wanted Club A and Club B to swap nations, then you would first have to move one club , say Club B, to a different 'neutral nation, then move Club A to Club B's old nation, and then move Club B from the neutral nation to Club A's old nation. It sounds complicated, but in practice it is not.
