Tactics, Formation and Instructions Against Slightly Better Team

Hello,

My team is rated 97% and the opponent team is rated 102%. This match will probably decide who will win the league. Could you suggest me what tactics and instructions should I use?

I play a 4-4-1-1 formation and I usually do not change it, as my sub players are not as good. The opponent uses a 4-3-1-2 formation.

I usually play:

Team Mentality: Attacking.
Focus Passing: Mixed.
Passing Style: Mixed.
Force Counterattacks: On.
Pressing Style: Low (I tend to change this one to high in tough matches).
Marking Style: Zonal (I tend to change this one to man-to-man in tough matches).
Play Offside Trap: On.

My team level: 2.
Season: 2.

Please help me.
