Not sure if I'm allowed to post this 100%, so I'm sorry if I've done anything wrong.
What it basically is, is the Argentinean and English top two leagues have been swapped around, this was done so that the two English leagues would have a limit on four foreigners able to play in each game, in the league. Unfortunately, the FA cup and League cup could not be incorporated into the new English leagues so had name changes to suit some of the Argentinean teams that would be also participating in the cup. Finally, you can still play in European cups with English teams and vice versa for Argentinean teams.
