Select maybe three or four of the best teams for you to control as more than likely one of them will reach the final!
Sim every match until the final and make sure your playing against a computer team in the final and not one of the teams you selected at the start, then make sure you play the final game 5 minute and on easy and win the game and you will get the achievement!
Very easy and quick to get it this way as simming the world cup only takes 5 minutes!
Good luck
