These tactics allow you to defend and press in the best way possible with a compact high line 541 and also you will be able to create a lot with the ball attacking with a 3421. LWB and RWB will go to high areas while LM and RM will go inside to play between the lines behind the strikers. The best way to play these tactics is by focusing on wing play, because you will have a 2v1 (LWB and LM against RB), if there is no space in, for example, the left wing, then going to right wing and trying the same.

Players will vary between forward runs and coming short. The team's transition to their in-possession shape will be steady rather than sudden.
A riskier approach to defending, applying situational pressure, and adopting a high line that tends not to track opposition runs.
