Ok mate for arguments sake, the new owner gives an amount he is willing to bankroll us with, the remit get the best you can for the money, and we can get VVD, your logic is we shouldn't as we should be able to get the player before his stock rises too high, basically the strategy we employed under Moyes time here, and how exactly did it progress us past a certain point, or did in fact we hit a ceiling where those bargain buys could get us so far and then we'd stagnate - because the oens above us where bringing in ready made players at a top level.
The forum by and large thought Niasse was gonna be a great signing for us btw, it also thought Deulofeu would be getting bought back by Barca.
What your describing by young players before they make that huge jump in value - is effectively moneyball, it's what the rs are in the process of doing and arguably what a lot of continental clubs survive by doing
the job of a very good DoF is all about getting the best players possible for the money spent and available, young players for what there value may become, older players for the impact they can have outweighing the lack of resale value.
The much lauded Monchi btw has some utter turkeys on his CV, including one Arouna Kone, the record signing at the time for Sevilla, 12m, he scored 3 goals and has 1 assist in 53 games for them
As for not having loads of money, honestly mate - none of us know how much we have, if the owner is willing to pay 50m+ for Koulibaly whilst actively bidding on other positions and players then we can assume roughly we aren't broke
