Funny thing is it is not only the cb´s,its the fullbacks too.
Shaw and Young cant defend and dont attack properly. They play in a no mans land.
Come to think of it,whom of the first XI are United material?
DeGea(yes)-Young(no)-Smalling(no)-Lindelof(no)-Shaw(no)
Matic(no)-Fred(no)-Pogba(yes)-Mata(no)-Rashford(not yet)-Martial(yes).
So much money spent on what? I think Bailly is United material with another manager. Dalot looks promising.
I would go for a younger lineup with a 4-3-3 formation.
Bailly-Smalling-Lindelof-Dalot(yes Bailly can play rb and Dalot lb)
Pereira-Herrera-Pogba
Lingard-Rashford-Martial.
