nah, doubt Pep would play Alonso and Busquets at the same time when he has Xavi, Iniesta, Fab and Pedro available. And would probably never go for a player as static as Arbeloa at RB but either Ramos or Iraola (not called up now but very similar to what Alves provides at Barca), depending on the LB, I guess.
mid would probably be Iniesta/Alcantara - Busquets - Xavi, and up front Mata/Iniesta - Fabregas/Torres - Pedro/Silva.
Del Bosue's tactics and utilization of his available personnel have been subpar to say the least, playing up front with 3 attacking mids, who generally lack that cutting edge and ability to score and look only to pass the ball to someone else ... someone else who is usually not there as no one is making the run, hence the lack of penetration.
On top of that, he tends to put on a pure winger like Navas, who's natural instinct is to cross the ball in the small PA, without a pure striker up front but midgets like Silva or Fabregas, who stood no chance vs the tall CBs of Croatia or Portugal, for example. A pairing of Navas and Torres/Llorente would make some sort of sense but one of Navas and Fabregas is a headscratcher, very much like the results it has produced.
