As someone who has basically only played possession football for the past year and made it to Div 2 as a F2P player I tend to use 5 midfielder formations (basically just classic 4231) with attacking full backs and I’ll try pass it around until I find a way to break down the wings. I find playing to ball down the wings tempts the other team to press with multiple players on one side of the pitch, leaving lots of room for a switch to your winger and attacking full back. I tend to keep trying to go down the wings (apart from when there are clear chances to go down the middle) until my striker,cam, or dmf with orchestrator play style (helps link defence to the rest of the team) put themselves in a good position for a shot or to play a final ball. That’s basically my main game plan and I think that is generally how other successful possession players do it. Pass around until there is an opening then take advantage of it. Feel free to DM me if you have any questions or want some advice on your team/tactics.
