Only does not work if you try to hoof the ball to one of the strikers. If you play with the ball down, with midfielders who know how to play (Barella, Brozovic, Eriksen, Sensi) it's far better for us to move the ball up front by sitting deeper. Also means that ball stoppers like Young, D'Ambrosio, Gagliardini and Lukaku himself are not participating, otherwise the element of surprise and the fluidity of the ball and player movement goes out the window and we're exposed at the back.
