Who went to the concert of One Direction.. only for directioners!?

Hi guys =) I'm Julia and I'm 15. Sorry for my bad english, but I'm from Italy.. This question is ONLY for who went to One Direction's concert.. I want to go to Where We Are Tour 2014 in Italy, but I'm soooooo preoccupied because I want to buy the ticket MORE CLOSE to the stage !! But unfortunately those tickets end up before because everyone want to see the guys near them :) So, if u know someone that went to the concert, please contact me ! this is my email. jennajakematty@yahoo.it . I wanna know how long before I have to buy the tickets, and which site should I use to be the first to buy the tickets? Please, help me ! I really want to go to the concert, I've been waiting three long years.. and now that I have the possibilities I'm so exited !
