That's the way I did. And I'm level 2.
you don't need to do any of that with facebook. all you do is go through friend list, or ucl leagues or cup games and click the managers asso and keep doing to until you find an OPEN asso. then enter it, come out and BINGO, the asso is unlocked (even at lvl 1)
