Defend deep, build up short passing to slow the game down and maintain possession until the CPU makes a mistake - which is rare, and stack your midfield to recycle the ball sideways while you wait for the opening. Triggering runs is important too.
Despite the fact this is what I try and do, the best way to score is usually still a counter attack. In Champs/Gauntlet I use 4213 - and I refuse to use women in my side - I have no fun playing with players I don’t know - just so I’m not like every other squad.. but against the CPU in SB’s, if you have to do the META overpowered stuff.. do it.
