Start an international league. Select only two teams to enter the league.
You will only have to play two games and will earn match winning points and 1,500 PES points each time you win the league.
In the Master League menu after you do the "Regulate Condition", sometimes you will have important players down. If you want to change that, go to "Next Match". When the screen with the teams' uniforms appear, return to the menu and do "Regulate Condition" again. The players will recover.
