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.
The ex-Arsenal trainee has made just one Premier League start this season and his manager admits the stylish midfielder is intent on seeking first-team action elsewhere.
“David would like to move, there is no doubt about that,” he said.
“He feels he needs to move on and play.”
Meanwhile, team-mate Pavlyuchenko has been strongly linked with a return to his homeland and former club Spartak Moscow, as well as Premier League rivals Arsenal and Liverpool.
The Russian netted 14 goals in all competitions for Spurs in his debut season but has found opportunities limited following the arrivals of Jermain Defoe and Peter Crouch.
Redknapp, however, still harbours hopes of hanging on to the pair and insists he will not be rushed into making any hasty decisions.
“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.”
