on what? transfers? tactics? You need a CB and probably I winger to rotate, I got Stefan de Vrij and Bernard, both on last year of their contract so you can get them for about 18 mil US $ each.
I have a hella basic 4-3-3 with a DM on Standard with retain possession, play out defense and look for overlap and I am undefeated all the way up to February.
When the team is that good the tactic don't really matter as much just make a basic formation and add specific instructions depending on how you want your team to play
