Go down to "Game modes"->"Create Tournament"->"New"
Other than the default settings, you should change the following:
Gamelenght to 2 min
Difficulty to Amateur
Tournament format to league
Number of teams to 10
Fixtures Vs. Each Team to "1"
The last is very important. It means, that you only have to face each team once!
As your own team, you should choose Brazil
And as the other nine, pick the crapiest, which are:
Andorra
Azerbaijan
Estonia
Faroe Islands
Liechtenstein
Luxemborg
Moldova
San Marino
Saudi Arabia
You should win the most of the games, but its not a problem, if you have a couple of draws. Just check the scores between matches. If you loose to many games, quit out to the dashboard, before you save the progress and start over!
