According the official barca site, VG is trying to re-schedule the 2nd leg cup tie against Atletico because most of the team will be playing internationals!! 
It may be impossible to change the date, so there is a possibility that barca will need to field a b team almost.
I hope that this isn't going to be as bad as it seems, and maybe VG can convince the national teams to not call up his players, because they are just friendly matches i think.
So, maybe we'll see a team a bit like this:
Arnau
Puyol Cuadrado Rosa? Bermudo
Xavi
Gabri Mario
Babangida Rivaldo
Rubio
