hi guys, beginner question here

My team plays sometimes in heavy midfield formations such as 4-1-4-1 with force counter attack set. In the game I end up with 60%/70% possession because of bonuses etc.

Does it make sense to play counter attack when you win by far in possession?

And related question:
Does it make sense to setup a formation with an undersized midfield but larger defense and attack so as to deliberately lose possession and play counter attack?

thanks
