The Barca midfielder has been superb in this month's tournament in Indonesia.
Darvich feels the move has improved him and said, "I think so because it's something completely new. I'm living alone for the first time, and being away from home is sometimes difficult at first.
"But I think it improves week by week and that's why I'm satisfied."
Darvich says his great football idol is Leo Messi because "he is an incredible player and because he has a good left foot, like me".
