Agree. He uses Barcelona as an example, top of their table and in the CL semis. Seems to work quite well for them even though the message is they concede more goals from their own goal kicks*.It's definitely not dead. But as a we do it every time, it's just the way we play mate, sort of ideology, it might be.
It's still a great way of getting space in behind, but you need to keep the opposition guessing. The if you've got a keeper who can go short, mid and and long, and signals that the players understand where to move and when, then it's hard for the opposition to defend all the people and spaces.
But yeh, we're miles off this in terms of tactics and personnel
* see my post above.
