I suggest you try to look at actual games and evidence. We were sliced open but not because we tried to defend or whatever but because we pressed too high and couldn't recover anymore, we were dead in the second half. We tried attacking, tried pressing high, had 55% possession in the second half and got thoroughly outplayed on the counter and beat physically to every second ball.
In Amsterdam we had Cancelo, Sandro, Pjanić, Bentancur, Dybala, Costa, Bernardeschi and Ronaldo in the second half, they couldn't hold the ball together.
