Since you made it to the final you have a good team. As far as he has giving you a room to think about his 4-3-2-1 then I suggest you also give him a room to think about this 3-4-1-2 short passes which you have possession at midfield. With this formation set one-on-one man-marking.
Give only attacking arrow to Your AMC and one striker to disturb his defenders. If you have a goal then in Second half you change one striker or AMC and bring defender adding strength in the defence. And give the rest at the front arrows second half
