I need to find time to watch the game in a state of calm but my feeling is that it's not so much that the defence was all over the place in some sort of disorganised fashion as much as we push men forward, in a very delibertae organised way but if team manage to break on us or win possession back high, which I beleive Newcastle did more than has happened in Pep's time in the league bar one other occassion, it leaves us short and then you do look all over the place.
It also probably didn't help losing Ake as the team would have prepared the game on the basis of the Stones / Ake partnership. A small thing, given Stones / Dias are hardly strangers but still not helpful.
