Azpilicueta is also an option for our board, I believe.
And about the poll: I can't say. I can't comment players I'm not aware of. But speaking of Azpilicueta, compared to Van der Wiel - he has the La Liga experience, of course. Plus, a player who was a part of Spain's preliminary WC squad can't be bad.
The problem is that the Cantera players you have mentioned are far too inexperienced to play a first team role, they barely get into Barca Atletic, they play for Juvenil A mainly. Except for Bartra but Bartra is mainly a CB..
Yes, but these guys won't have a first team role in the way it sounds. (as a starter or something)
Remember that the main idea is to have someone for an Alves back up. And if Alves is missing in an important moment and Pep feels that Bartra/Montoya/Dalmau/Muniesa or whoever else can't deal with it, we have our universal soldier covering all types of holes - Carles Puyol
It's true that experience is more important for defenders than midfielders or attackers, but Barca's season offers a lot of good moments for the youngsters, like 1/2 of the Camp Nou games for example. Where everything goes pretty smooth and the young guns won't play under a big pressure.
