Hi guys

I'm thinking about playing with only 3 defenders at the back. I need some of your opinions and experience.

1) 3DC or 3DW?
2) if 3DC, how would you deal with AMR/L?
3) if 3DW, what if there are two STs?
4) and what would you do if you're playing against mixed focus side like 4231 with AMRLC?

Thanks guys.
