That's just playing how selective can I get. Drawing a line where it suits a made up point.
It is no different to arguing Haaland and Alvarez are already part of the squad, so who replaces Gabi and Raz, well not those two as they are already here.
At the end of the day, Haaland is replacing Aguero. Khaldoon literally said it in his Interview, Pep said it too, less directly. Doesn't matter that it is a year later when we made do while we waited, and it showed in 3 competitions. And Alvarez is replacing Torres, doesn't matter that he was bough 3 days after Torres was sold.
If now both Raz and Gabi leave, still leaves us light and needing a new solid player in. Not Grealish, not Palmer, but an extra body. We could probably spread Jesus' role among the team, and we might even make do without replacing bot, but it would be just that, making do till someone can be brought in again. And why, why compromise 2 years in a row, particularly after spending on Haaland and Alvarez instead of getting the most out of them with tge right squad.
The window is yet to open, both players are yet to leave. Plenty of time to replace one of them if they get sold, lets see how it plays out.
