Presuming we sign 5, I reckon we'll sign a RB, CM, RW, ST and a CB/CM. I'm going with CB.
I have 4 sets of transfers in my head, 1 is my preferred (i.e. literally impossible), 1 is an Ed Woodward galactico set, the third is a realistic/Ole type set, and the other is if Ole really wants old school and has gone off the deep end:
My Preferred (Dream) Choices: Wan-Bissaka, Ruben Neves, Sancho/Pepe, Griezmann, Skriniar (Part of Swap Deal with Lukaku).
Ed's Choices: Cheap young Right Back (no market value here), Coutinho (This is Ed so for CM), Bale, Dybala/Griezmann, Varane.
Realistic/Ole Choices: Meunier, Declan Rice, Someone like Buendia/Brooks but would prefer Sancho, Dybala/Icardi or a Dembele/Ayoze Perez, Alderweireld.
Old United Ole Choices: Rafael, Drinkwater, Josh King, Danny Welbeck, Michael Keane.
