Ok, but we can start by buying Ajer in January, that isn’t very expensive.
Then in the summer we will see of it’s possible to sign Camavinga or any other good midfielder and in 2022 we must sign Haaland.
Btw, It’s true that Van de Beek was cheaper than Camavinga, but he is useless for United, he plays mainly as an advanced midfielder, a position where he doesn’t offer anything more than Bruno Fernandes, that is a much better player;
Camavinga is a more complete midfielder, with defensive and offensive skills, he can play instead of Matic, while vdBeek doesn’t.
It’s better to spend more for a useful player, than spending less for a player that won’t even play as a starter!
