For those curious about how the position changing with the DPad works:
Essentially you have your same starting formation and tactics as you like. Now Attacking, Ultra Attacking, Defensive and Ultra Defensive can be set up entirely from the squad screen where custom tactics were before. Each setting can be whatever formation you like, with players in whatever position you like, with whatever tactics you want all ready to go by clicking left or right on the dpad.
For example, you have Best and Ronaldinho and you want both as your strikers in a 41212. Start off in a 433 or whatever and just have your 41212 setup attached to your “Attacking” option with those two up at striker. Click right on the dpad once at the start of the game and you’re good to go. It’s easily my favorite new feature this year and makes for some really interesting tactical moves throughout the course of a match.
