need to enhance Butterfly tactic for Cup final

[jihado86]

Hi, today I have a cup final against 3-5-2 flat formation, so I'll use Butterfly formation to counter his ..
is there any additions in the settings (passing style, tackling, pressing, team mentality, marking, counter attacks, etc ...) also the arrows ..
knowing that he's level 12 and he has players with Q81, 79, 78, 76, 75, and some between 70 and 74, and I am level 11 with 4 players Q75, 4 players Q74, 1 player Q73 and 2 players Q72 ..

this is my first cup final ever, and my 2nd time I make it to the final 16 (last season and this season) ..
I believe I can win .. but I need some advices ..
