Both have struggled to secure first-team football after falling down the pecking order in recent months and look destined to leave White Hart Lane in the New Year.
Spurs splashed out almost £30 million on the twosome 18 months ago and Redknapp has insisted that they will not be accepting knock-down prices should they be sold in January.
“It is up to the chairman and whether he gets the money and it is the right offer,” he said.
“I would not let them go cheaper. Otherwise you end up giving them all away.”
Bentley arrived from Blackburn Rovers for £15 million but has largely failed to live up to the expectations surrounding his big-money move.
“David would like to move, there is no doubt about that,” he said.
“He feels he needs to move on and play.”
“Obviously Pav wants to move but we are not mad to sell them. They are not going cheap and are both good players,” he added.
“I won’t let my emotions get in the way of the fee we get for Pav and Bentley.”
