You're new here, right?
All those other teams have shown that when it comes to the crunch they are more than willing to pay big bucks (whether that be transfer fees and/or wages) to get that signing that is undoubtedly a 'step up'..we on the other hand...well...
We got 5th last season and had clear areas to improve for Ange: Striker, LCB, LB....we saw what we saw and i still don't know what makes people think (apart from hope?) we'll be any different in the next window or two.
Buying young and cheap is what our owners are comfortable with and i don't really see that changing until our ownership model does tbh.
You might call their plan naive but i call that them being consistent to what they are and have always been comfortable with
