How to unlock the First Team Selection achievement in 2010 FIFA World Cup - Definitive Guide
I would play all the CYC on amateur just to make it faster. Set it to 4 minutes because you do have to play around 20 full games. You get this when you get called up. Friendlies matches won't net you the trophy. If you play 3 straight good games of 8.0+ you should get called up.
