£30m for Romero.
Noone is going to pay that you loon. He is also 30, as opposed to Pickford who is 23 (so Everton can get at least 10 years out of him).
Blind at 15m and Mkhitaryan for 20m maybe, but doubt they could actually be sold for that, especially if you take into account which clubs could afford their wages in addition to a hefty fee. Darmian at 15m - also not likely. Realistically you would be looking at getting 5 for Romero, 18 for Mkhi, and 10 each for Darmian and Blind, assuming you could sell them at all. So would be hard to get 50m, let alone 100m.
