Yes, this.
In theory...and so forth.
But also - yes, why the feck not?
In the absence of any midfield signings - sure, yes, try the fecker.
The thing is that we have strengthened considerably at the back now. Varane/Maguire
should be a very solid pairing - which
should mean we need less of a rock solid defensive presence in the so-called double pivot.
Perhaps a clever (movement) and tidy (passing) player there is enough - not least if that player is adept at (simply) transitioning the ball effectively: as in, he doesn't need to be a great passer/playmaker.
The basic setup (a 4-2-3-1 variation) doesn't really require either a) a defensively rock solid DM or b) a playmaker.
If the front four works well enough:
Sancho (Greenwood) ---------- Bruno ---------- Pogba (Rashford)
Ronaldo (Cavani)
...we could get away with fielding a functional but not spectacular "pivot" behind. But that pair cannot a) get overrun easily and b) give the ball away for fun.
