I just want to indulge for a minute in this muppetry. So, Sancho 80m, Varane let's say 40m (it's unlikely they get that price they probably put feelers out on), Kane 120m. 240m, not counting agent fees and wages. Let's play the hypothetical subjective game:
Lingard out, 25m (best case scenario)
Dalot out, 10m (best case scenario)
Martial out, 40m (don't think this is the time to sell him, low stock and will be useful on the left, but we'd definitely need money if we were going on a spree)
Pereira out, 3m
De Gea out, a fee high enough to cover half his wages for the remainder of his deal which over two years is 40m, so 20m and half his wages subsidised (absolute best case scenario) - zero net overall
Bailly out, 12m
Matic out, 8m (to Roma)
Mata end of contract
Romero end of contract
Grant end of contract
98m in.
In terms of wages (all rumoured)
de Gea 375K
Bailly 80K
Lingard 75K
Matic 120K
Martial 250K
Mata 160K
Romero 70K
Grant 30K
Dalot 25K
Pereira 30K
That's more than 58m annually in wages saved. Not astronomically insurmountable, but would represent the biggest outlay since the wild west of Mourinho and LVG.
Caveat 1: I don't think either de Gea or Henderson is what we need, but selling Henderson for 30m would bag Donnarumma's "free transfer" with view to Raiola's cut, alternatively, we see if there is even the slightest chance with ter Stegen
Caveat 2: If Pogba goes, I'd expect us to sign a midfielder who can pass and is good on the ball, but let's leave that out for now.
