Trying to be realistic, but also optimistic:
-A new right footed CB. Preferably someone that can pay centrally and RCB. Lenglet isn't exactly world class, but a right footed player at his level and with his attributes would definitely improve us.
-A Kulusevski option. I quite like what I've seen from Malinovskyi and he shouldn't be that expensive. But we need someone in addition to Kulusevski that can play that role. Again, doesn't have to be world class or anything like that. Though better is obviously better.
-A right wing back unless Conte thinks Spence can make a difference in the second half of the season. This is where we should be willing to spend the big money if we have that available. Starting quality, someone Conte can trust.
