I need advice on formaiton and tactics urgent please

I am playing against a team tomorrow I had a really hard time in the first leg and at home, I tied 1-1 after leading 1-0 all game and got tied in minute 82. It was rainy though and my team does not play well in rainy weather. Tomorrow's match will be in ideal but I am playing away. The other team's quality is 110 % mine is 117% so we are close. They play with a 4-2-3-1 DR-DC-DC-DL MC MC AML AMC AMR ST

I am going with a 3-2-2-2-1 DR-DC-DL DMC DMC MC MC AML AMR ST I think it's the best-balanced team in this case. I need to know the right tactic to play against him. By the way, my team almost always loses when I play defensive or normal but I was thinking this time to try NORMAL-DOWN BOTH WINGS-MIXED PASSES-NORMAL TACKLING, MAYBE EVEN EASY BECAUSE THE LAST TIME I GOT BURNED ON A FREE KICK that's how they tied it. LOW PRESSING-COUNTER ON-OFFSIDE TRAP OFF ZONAL MARKING

ANY ADVICE FOR ME?

Hi Marco, i'm Marco as well :)
Imho the tactict you're using against 4231 is wrong due to you're not creating numerical superiority in any field's side (except for DMC), and you're having a one-to-one man in defense.
Usually, when i'm stronger or equal of my opponent, i'm using a 41212 against 4231: in this way my defense is numerically greater then the opponent, and i have a TC without marking.
About tacticts, i can use Centre/Mix passes or Mix/Short passes either, depending on the MCs of my opponent.
Normal, No-Counterstrike, Low Press, normal tackle, zonal marking, yes-offiside the rest of tacticts
