I was less impressed by Thiago and Jonathan. The former in particular had a poor game IMO. In the first half he gave the ball away with every single attempted pass. And both of them still have a lot to learn in terms of positioning themselves and making themselves available for the pass. Jonathan seemed invisible in the game, and as for Thiago, too often he would ask for the ball in a position where it's either just too difficult for the passer to give it to him, or even if he did get it, he left himself a lot of work to get away from defenders and do something useful with the ball.
Interesting formation from Pep. It was a 3-4-3 with the following setup:
Pique-Busquets-Fontas
------Mascherano------
Jonathan----------Maxwell
---------Thiago
Jeffren--Bojan--Adriano
I don't think the formation worked. Busquets was excellent as the lone CB, and Mascherano's link play was also good, but the left side was the only outlet, and quite overloaded with both the wingbacks there. Jonathan didn't stay wide at all.
Once Pep was forced into changing to a 4-3-3, the football flowed more comfortably. Bartra was a natural outlet on the right wing, and with Maxwell playing at LB, this allowed the field to be properly stretched. The passing patterns going forward also looked much better.
Bojan and Jeffren didn't help themselves by getting injured. I think after this season, neither of them have a future at Barça. We'll need at least 2, perhaps 3 (if Afellay will play in midfield) reinforcements for the attack.
