I played last night against this formation using 4-3-1-2 and won 1-0 but my team is 9 points above in quality than other team!

I always have problems against that formation... don't know what else to try!

It's CL 1st leg game and it was home game, so with my team I thought I could get some more goals

We bot had same shots on goal, and I had 2 or 3 extra shots on target.
My keeper 1 save and opponent team 2 saves.

What do you think?

Should I buy a ML and MR and copy opponents formation for away game?
Or maybe play 5-3N-2? (against 5-3W-2) and play deffensive just in case? hehe
