The whole point of this though, is that Pep doesn't want other teams having shots for our keeper to save, and his idea is to prevent them, is by NOT giving away possession in the first place, so shot stopping is not as important as distribution.
I don't understand why people can't get their heads around this idea, and the (albeit limited) evidence so far, is that we are already having fewer shots against us, and this with a keeper who isn't the best at playing it out from the back, and a defence that isn't yet used to it.
