I am inclined to disagree with the fact the Rooney sale moved us up another level. Firstly, we never recouped the full transfer fee for Rooney upon completion of his move to United, secondly, we did'nt exactly buy massive to enable us to move a step further. That has been achieved by Moyes foresight to work on a small budget and having the ability to get the best out of his players.
The season after we sold Rooney we spent £20m net on transfers. So clearly that money helped.
