It’s hard but it’s not impossible. I’m a Div 6 player in rivals, I’m awful. 7-8 every week in Champs.. but SB’s so far (i’ve completed 4 weeks and played 10 so far this week) I’ve won 80, lost 2. Most of them on legendary, some on WC & some on professional - my latest win last night was 4–1 against an 88/33 side. Also won all three penalty shootouts I’ve played… you can’t play against the AI like you do online, it won’t work. You’ve got to be patient in attack & defence. My biggest legendary win is 9-0.. it’s not impossible (unlike Ultimate)
