Yeah, didn't like that article. It starts with the premise that Pep prefered a small squad of 14 or 15 first teamers as if this is the only valid way to coach a team. Completely ignoring how stacked his Bayern side is. Bringing Götze, Müller and Javi Martinez from the bench in a CL semi-final while Thiago didn't even participate at all due to injury.
Barca's options in such a situation would be Tello, Song and Sergi Roberto.
For me these are the players who have the standard to be Barca first teamers right now without any shadow of doubt.

Which means we are lacking about 5 players.
Upfront both Pedro and Alexis are close to being starters ("first 14", first ones to be subbed on) but not at the elite level to be definite starters in all situations. Both rely too heavily on others creating for them instead of creating on their own.
In midfield Xavi needs to replaced. Fabregas is not the answer.
Entire defense has to be restructured. An elite CB like Benatia or Hummels, a more physical leftback like Mathieu (I'd ditch Adriano, I don't understand what he's doing in the squad, too similar to Alba, always injured, can't defend, midget ...) and a rightback who is not a clown. Yes, at this point I'd even give Montoya lots of playing time and see how he grows.
This is just the starting XI for me. We're not even talking about depth yet. A physical presence in the mould of W. Carvalho instead of that clown Song, the option of a proper #9 etc. is also needed.
