Of course, it's adventurous. But he tried it twice last year against Chelsea and we were unlucky, with worse personnel (Delph Clichy, Navas all started the second game, Nolito also made an appearance, Caballero etc.) Danilo aside everybody would be playing in a natural position.
The way Pep works isn't to try and double up on Hazard, or Moses etc. But to stop the supply in the first place. And he has the ballers to do that in midfield by retaining the ball, and the wide players to keep their full backs on their toes.
