I gave these orders a chance (i've been playing 4-5-1 V-style for some time now) and they proved REALLY ineffective. With all my defenders and DMC on blue arrows, low press and man-to-man marking, the opposition really tore my defense to shreds!!! They kept passing in my penalty box to their liking, managing to bring the ball in the 6 yard box at will and shooting from close range! Sorry, I don't know how this can work, I find zonal marking and hard pressing a better option. Every time I've played with low press the opposition gets in my penalty area with no problem and can arrive close to the goal without being contested.
