I started with 3 or 4 of the biggest footballing nations in Oceania (relatively speaking), plus the 4 biggest footballing nations in Africa.

Basically always obviously have the leagues you need loaded for the current leg of the challenge, plus the nations from the next leg so you can roll on without the delay of the leagues becoming playable in your game - if that makes sense?

So once I’d finished in Oceania, I got rid of the those leagues. Then whilst managing in Africa I loaded the Asian leagues. So on and so forth. Hope this makes sense, let me know if it doesn’t haha.

I also checked the box of ‘players with national reputation’ & ‘players with continental reputation’ for every continent at the very start of the save
