May be hard to see, plus being in Spanish, I will summarize.
- Goalkeeper Victor Valdes is a current exit candidate that he himself has announced. Second goalie Pinto stays
- The current defensive line up stays: Alves, Pique, Puyol & Alba. Including the theoretical "alternatives": Montoya, Bartra, Mascherano & Adriano
- The backbone of the midfield is "untouchable": Xavi, Busquets & iniesta.
Alternative option Thiago untouchable, BUT Song & Dos Santos transferable & on the market.
- Forwards: Pedro & Lionel Messi untouchable, BUT Alexis is on the market, along with David Villa whose future is uncertain. Cesc & Tello will continue.
- Players on loan like Affelay & Bojan are on sale, along with youngsters Cuenca & Fontas
- Young promises Sergi Roberto & Rafinha have an uncertain future, but Deulofeu is untouchable.
I have no doubt this will be changing in coming months.
