You sound like you're at your wits end with the toffee's mate.
No cash no hope?
If he's worth it or not, if they can grab a silly cash sum for Rodwell, they should. Managers really do seem to forget this, quite a lot of clubs buy in cheap players on great deals and let them out to another club who pays a heck of a lot more. Arsenal, though we should never, ever have sold Diarra, made cash in the deal, Pompie made a buttload(of which Arsenal got some I believe but not a huge amount).
Everton have Rodwell to cash in on his potential and the sooner they do that the more they'll get frankly, Arteta could potential fetch a decent price, getting older and only had one "great" season. Cahill would fetch a decent price, but given the reliance on his goals, not sure that would be a worthwhile deal, Jagielka, 15-20mil maybe to a top club if he gets back to his best, maybe 10-15mil if lucky if he doesn't. Baines could potentially go for a lot.
Ultimately if Everton are willing to be a bit aggressive, sell some "stars" and get good deals in the transfer market they could do quite well.
Some managers are completely willing to do that, others aren't, and obviously its a risky game, but I can't see much other choice for Everton. Buying a Fellani for "big" money isn't working for them. Loads of uber cheap players and hope you get a couple decent enough players in amongst them, rinse repeat.
