No mate.
The youth teams should all be playing a similar style to the first team (with various tweaks) so over a period of time if they come through into the first team they each play the same way as they always have done -- same as the setup as La Masia which Cruyff changed.
Now, if the first team is all top notch and winning champions leagues it will be that only the best kids come through. If its sitting in 12th then more kids come through as the quality level is lower.
Buying in players would mean the bar is set higher. My thinking is that over the next 2+ seasons (after the 3 we have had) we will start seeing kids coming through which may even be Galloway/Holgate/Foulds types or local boys.
It sounds like we have Ledson,Walsh,Dowell and more on the verge now as well as Galloway,Browning,Holgate also who should all be with the squad in the summer.
What we desperately need this summer and the next and the next are a couple of players to come through.
Then we slot them in on the bench or give them games here and there till they are ready then sell the backup players to allow them to compete with our first choice guys.
Samr as Utd and Barca have done very publically.
