should be pretty self explanitory...
lee seung yeoul is supposed to be their next best thing from the academy- lee seung woo.  i'm hoping we'll get to see him in fifa at some point later this season.
diego reyes, i'm just a big fan of his.  id like to see him replicate the legend that is rafa marquez.
laporte is one of the best young cb's.  could go anywhere, but i think barca will be the most interested
hector bellerin, well... like most good ex barca academy players, they always end up back there eventually.
gaya instead of grimaldo because he's just a better talent to put it simply.
halilovic on the wing because he's left footed, agile and a great dribbler.  always causes the opposition problems when he runs at them and cuts on the inside.
correa is in there because he can run with the ball from deep in a sometimes messi-esque style.
verratti will need a step up in his career at some point.  barca like short players, so i think he would end up there.
