Of course. But it's still very much on an upward curve at the moment, so until we catch that ship, we are going to be playing catch-up. Poch is the primary protégé of the inventor of that approach (Bielsa), so there's probably no one better for getting us up-to-speed and beyond.
There will be a test for Poch in 5 years' time, when tiki-taka or counter attacking comes back (I consider Bielsa's proactive football to be a blend of those two extremes), and we'll seen then how smart he is and able to evolve with or ahead of the curve.
But whatever direction the game goes, I can't see creating an ultra-fit, technical squad who are disciplined and can transition quickly could ever be a bad thing. It's better than that the delicate, half-arsed chip-munchers who have filled our squads for the past 25 years.
GB I love you. Truly. However, it's such a simple game I just want to see us play 2 wingers and 2 up front at the Lane!!
