If we were doing that then we would be bidding right now to get those players. It would act as a leverage against clubs who are asking silly money for the likes of Fernandes and Scott. This is not just about transfers but also how we operate. We're so damn slow. Even the Ederson deal has yet to be completed, Meanwhile we're still 'preparing a bid' for Fernandes whatever that means. Not to forget that silly 'we want Eliot Anderson' propaganda that dragged for months only to end up with an egg on our face as we learnt that we can't even afford him. That's naive and amateur
Regarding the past SAF implemented a mix of transfer strategies which included cheap punts (ex Johnsen, Ole, Schmeichel, Vidic, Evra etc), old short term fixes (Larson, Owen, Goram etc), solid PL talent that offered value (Carrick, Valencia, Young etc) and the occasional breaking the bank for a young talent whom he was dead cert that they'll turn up amazing (Rio, Keane, Rooney). The highlighted part is key here. For example he humiliated Leeds for spending 18m on Rio Ferdinand because he wasn't sure the potential justified the fee. Few years later he had no problem eating ample humble pie by spending almost double to get him out of Leeds. That's because he had confirmed that he's going to be elite.
I very much doubt that SAF would entertain breaking the bank for the likes of Maguire and AWB as we did as much as I doubt he'd spend 80m for the likes of Scott and Fernandes who are good but who are nowhere near to a Rio, a Rooney or a Keano.
