To speed up the process of qualifying for a region, all you have to do is use 2 controllers. Make sure you are Controller 1, move to the opposing team and move Controller 2 over to your team. Then, all you have to do is FORFEIT the match with Controller 1 and keep on doing it as your team will get a default win of 3:0 and in the end will qualify for the World Cup, gaining all points. To forfeit a match, press when you're in-game and select the option "Forfeit Match" at the bottom of the menu.
For this achievement, you'll have to start another "2010 FIFA World Cup" campaign, and make sure to set the tournament type to "Qualification", so you only play the qualification for the World Cup.
Make sure to set the region to CONCACAF, select your team pressing , then press to advance and simply try to win all matches.
The qualification requirements for the region of CONCACAF are as follows:
Two preliminary rounds to reduce the 35 entrants to 24 and then 12 teams, followed by 3 semifinal groups of 4 teams with the top two in each group advancing to a final 6-team group.
The top three teams qualify for the World Cup, while the fourth placed side is entering a play-off with the fifth placed SOUTH AMERICA nation.
NOTE: Use the 2-controller method mentioned above to make sure you finish first and qualify for the World Cup.
