4-3-1-2 | Fluid football with lots of goals

I was on my first save with FCPorto, and after 2 seasons playing with a 442 / 424, i decided that i wanted a most solid defence but keeping the 2 PL's.
So in my third pre-season i invented this 4312, using inner overlaping and focusing my gameplay in the middle.

On my second season using it, i finally won the UCL beating Chelsea on the final on a 2-1.

I decided to share it, so i can have more opinions and see the results in other leagues and teams.
