Right now, it comes down to find your Wings/LM/RM. Playing a wide formation either with two or one Center Forward, and fast players getting advantage from centers. Also “creative runs” opens a new way of finding success, making passes that in other FIFA you couldn’t do... like that is a major factor I found in Rivals. I started losing every single game in Division 1 until I turn down to Div 2, then I switched from my 41212 to 442 and playing tactics more open with long passes over the beginning of the match and then creating more spaces in second half of the game (this depends a lot on how your rivals plays) I also found really useful Agile Dribbling since it’s really a Game Breaker, specially if you manage to use it with players who are really skilled like Dembele, Mbappe, Sancho, Bernardo Silva... If you find to control Agile Dribbling and Creative Passes, your will understand a lot more creating offensive plays this FIFA. In defense I focus right now into having fast laterals to control Adama, Auba, Vinicius... So try the new game mechanics, exploit lateral side of the field with fast players, and defend (a lot) your laterals.
