It's actually wrong really; it's even more of a gap.
I had Fellaini £60k, Neville £45-50k, Anichebe £25k... but then you've got a saving from Moyes to Martinez every week, and the backroom staff from all accounts, then Mucha £15k, Jelavic 45k, all estimates but not far off. So say around £200k a week in wages freed up.
Replaced by McCarthy on around £40k, Robles on £15k, McGeady £25-30k... and that's it. I don't count loan players, as they're one year deals; unless we plan on replacing like for like and spending just as much on wages next year for loanees then it isn't a factor.
So long term we're currently saving £100k+ a week on wages in the long term, have a transfer surplus of £20m approx (after loan fees that is!), yet we're dependent on a player with five months remaining on his deal to move on to back the manager in the pursuit of European football.
