I did it last year, I think it was my UCL/Libertadores Cristiano actually included in his DFL.
I haven't opened the game packaging yet even though I bought it a month ago from Amazon.com lol. But has there been any changes to the South American competition system from 2017? I can just find as many already made teams and edit them neatly, and create the rest.
Let me know and I'll get right on it.
By my side, I like MLS.
But Konami doesn't allow to play MLS because it's impossible to have an Eastern Conference and a Western Conference.
So, this year, I would prefer to have Copa Libertadores teams.
But, it's my choice and no the choice of everybody.
Impossible to satisfy everybody.
