I think that there are lots of different variables between the Moyes and Martinez transfer dealings...
Under Moyes, we were not as established as we are now, we can attract a different calibre of player due to our constant top 6 positions (largely thanks to Moyes)
Moyes did try to bring through young players,he showed plenty of Faith in big Vic/rodwell not to mention Osman/Hibbert and Rooney.
He bought younger players and generally bought well - Stones is his purchase lets not forget and had he stayed another year I'm sure barkley would have gotten time. He didn't have the luxury of the extra 25 money and he is responsible for a lot of the transfer kitty we have had available(Arteta/Felli).
Don't get me wrong, I'm delighted with the signings we have made and the path we are on, I just don't think it's too different to what we are doing now, we just have more funds available.
