Can anybody outline the major differences between these roles? They don't seem to perform a huge amount differently in the game as far as I can tell.
I guess the Mezzala is more like a deep 10 who doesn't contribute to defence as much outside of high pressing? And CM-A & BBM-S act like shuttlers with late runs to the box with the CM more of a passer than the BBM?
And in an attacking three-man midfield (with a DLP) what would be the best combination? Mez + BBM, Mez + CM, BBM + CM... There isn't much balance but is there something about one that would complement the other very well?
