Some questions about cup final and 4-5-1v style

[Bog Igre]

My opponent formation is below.I have a slightly better team.My bouth wings,one ST,one MC,LB and CB are 7* and a rest of a team are 6* but my team doesn't play good when i play 4-5-1v style.I usually play 4-1-2-1-2ND when opponent has AMC but this is one game and i don't whant to make any mistakes.His formation with AML is confusing me....should i play ND or risk it with 3W-1-2-2-2 my CB 7* his ST 6* and my DM is equal with his AMC.He is only beter on left wing his AML 7* my DR 6*.But whith what orders???And another question what are the ideal orders for 4-5-1v style?I read a lot on this forum about this is the best formatio bat AM always tell me that i should attack more and attack directly and when i turn to ND then i start playing football and score goals.And just one thing like I said his AML and DR are 7* the rest of his team are 6*players.
