We want 2 quality players per position. I suspect Roberts will be loaned out and Iheanacho sold. If we were to get all of our supposed targets (extremely unlikely), we could have for example:
Central striker - Aguero and Mbappe
Left sided attacker/winger - Sanchez and Sane
Right sided attacker/winger - Sterling and Jesus
2 creative players ahead of the DM/pivot - Gundogan, Silva x 2, KDB
DM/Pivot - Yaya and Fernandinho
RB - Walker and Fernandinho
LB - Mendy and Kolarov
CB - Stones, Otamendi, Kompany and Laporte
GK - Bravo and Ederson
Problem is that this leaves us with 18 foreign players by my reckoning. So in the unlikely event that we got all of those signings, we'd have to replace one of them with a HG player (most likely Kolarov or Bravo I would have thought) and it still doesn't allow us to bring in a new DM like Fabinho unless there is a decent HG one knocking about.
