Assuming w/ player sales:
Morata: 30m
Asamoah: 15m
Pereyra: 15m

60m IN - Lemina's 9.5 gives us 50.5m
50.5m + 40m budgeted for buys gives us around 90m to use. That's plenty IMO to do some great work in the window.
Could sell Zaza as well to add to that but at that point its sorta wrecking the lineup.

Alves: Free (if he even comes)
Lemina: 9.5

Personally, with what he would do for this team, I think Alves would be pretty fucking close to equal to Pirlo in terms of value to this team. Yes, pretty far-fetched even for my standards.
