Yes, and opponents know we are still learning to play this system - so they're primed to try and hurry us and force a mistake.
None of us know what's actually being said in the dressing room, so this 'playing out from the back AT ALL COSTS' is probably hyperbole, but we do seem to be playing as though it were true!
I like to hope Pep is saying 'if it's possible to play out from the back, do so - but otherwise, play it safe' and thus it's just our decision making on when it's appropriate or not that needs work. If it's true that we're playing out from the back at all costs - then I have no problem in sticking my head above the parapet and saying that's madness (even if Pep wants it).
