50k a week is still a bit excessive for players of the Brown/O'Shea calibre.
If O'Neill is given a lot of money to spend this summer, can see it going quite badly for them (going by his history with Villa). Sure, he'll be able to bring his "own players" in but he is somewhat prone to leave them out for no apparent reason (see Sidwell, Beye etc.). That'll mean money down the drain and the mackems' financial situation being, well, precarious. I mean, Villa are still trying to sort out their finances as far as I'm aware!
Also if Sessegnon does leave this summer, can really see them struggling next season.
