Redknapp is eager to overhaul his squad this summer.
He said: “It’s not easy to shift players. It’s hard to get them out when they are on good money. They won’t suddenly walk away on good contracts.
“We need someone to ring up and ask before we can get rid of them. We can’t chase them otherwise you are leaving yourself wide open. It has to be the right deal for the club.
“I’ve not had any calls. But then they don’t ring managers too often now.
“Deals are done by chief executives and chairmen.”
