france played 4-2-3-1 for the majority of the 2018 world cup and their double pivot was kanté - pogba. arguably the last time pogba showed great form on a consistent basis.
besides that, sandro has to leave and we need a starter lb
kean didn't improve too much unfortunately, he's only effective when he's got space. morata is easily the better player, unfortunately he's the best 9 we have. all we can hope for is some happy holidays for morata. his form from the first part of last season is much needed.
IIRC France played 4-3-3 but even if they have - We dont have someone like Kante and besides that there is probably no other player with Kante`s characteristics who is on his level.
4-2-3-1 could work for this season as our mid is crap but we need to execute it better.
Next season - If we get an attacking minded midfielder like Pogba we must play with 3 men midfield.
A.Sandro isnt performing - This is obvious and we do need a new starting LB but we have much to fix before that position.
As I see it we need by that order:
CF
CM (attacking minded)
CM (Great at defending but also pushes forward)
LW (We actually have none..)
LB
GK
CF because all our starting ones are crap and even when there is someone that plays well he gets injured anyway (Yeah I was referring to Dybala).
