Bale is one of the most talked about players in Europe, having twice this season tormented European champions Inter Milan in the Champions League. His form in the Premier League has been of a consistently high standard and his wicked left foot has seen him become the subject of widespread transfer speculation.
It was claimed this week that Inter were readying a summer bid believed to be in the region of £40 million, although this was swiftly played down by the Serie A giants. The chatter has not been missed by Redknapp and he has once again made it clear that Tottenham have no intention of selling a player they bought for £5 million from Southampton in 2007.
"We won't be selling Gareth Bale in the summer, it's up to the chairman but I'd be very surprised if we were interested in selling him at any price," Redknapp said. "You have special players in your team and if we're going to be a top team you've got to keep your top players, you can't be selling Gareth Bale.
"You've got three or four players who can make a difference and he's one of those players. And, if you lose him, you can't replace him. Where are you going to replace him? You go and get one from here, one from there, another one.
"When he gets the ball something happens, he can do something that no one else can do. We can't afford to lose him."
Redknapp has revealed that midfielder Tom Huddlestone has suffered a setback in his bid to return from the ankle injury that has sidelined him since September.
"Tom's had a setback and it seems he's going to be longer than we expected," Redknapp said. "His ankle is sore. He tried to do a bit of running and is still a long way away.
"We will have to look at his situation with regard to the 25-man squad. I am hoping he'll be okay as he is important to us and is a fantastic player."
