No mate, what you've said is entirely wrong. if Pep has spoken about his midfield having many touches (I don't know that he has) I'm almost certain he means that in the context of passing quickly, making the pitch big, shifting the opponents and tiring them out by constantly passing, the literal opposite of what Grealish typically does when he carries it.
Peps football is all about moving the ball, one thing Pep has definitely spoken about many many times is how he wants the ball to do the work by passing it. he doesn't even have a fondness for players dribbling out wide, he certainly doesn't want it deeper in the central position. I've no idea how after all this time but you've totally misunderstood one of peps core fundamental principles, he talks almost every single interview about moving the ball quickly.
