Everton chairman Bill Kenwright has assured Roberto Martinez he doesn't have to sell their best players.
Marouane Fellaini and Leighton Baines have been linked with moves away.
"He talked about a couple of new signings and he talked about the squad and asked 'Do they need to go?'," said Kenwright of his discussions with Martinez.
"I said 'No, they absolutely do not have to go' (although) there is one (Fellaini) that has a get-out which everyone knows.
"I said to (Roberto) 'I can't sit here and give you a line because we all know money is everything in football - this is the money we've got and I will try to improve on it.
"We are desperate to find new owners and new investment but he will get support from everyone at the club and all the financial support - and by that I mean if he sells someone he won't get 80 per cent of that he'll get 100 per cent.
"Plus he has a certain amount of money for the transfer window which David was going to have."
