Liverpool won the PL because Klopp stuck with Mane, Firmino & Salah when all three were fit. I can’t see Ancelotti moving away from James, Calvert-Lewin & Richarlison after the start they’ve had.
Play your best players in their best position in a system they’re comfortable with.
The only conclusion I can come to is that Cox doesn’t yet know his best players or has been forced by injury (some may say because of an imbalanced squad) to play a system that they’re not comfortable with.
I’m also wondering if there will still be movement in and out before the window closes.
