I'm just awful at the back that's why I was thinking about playing 5 at the back.
I think 5-3-2 could sound like the best idea.
Yeah, I agree. CF, RF and LF just annoy me, as positions.
But that said, I was trying to sell you a CF earlier

edit: 5-2-1-2 might be ok.
A slightly more attacking version of 5-3-2.
