The permanent signing of Juventus loanee Yago Falque has been the only bit of business the Barclays Premier League title chasers have conducted this month despite a host of names being linked with the club.
Christopher Samba, Junior Hoilett, Loic Remy and Bruno Uvini have all been mentioned as possible targets for the Londoners and a number of fringe players are also keen to leave for pastures new.
Redknapp and Tottenham chairman Daniel Levy have become famed for pulling off 11th hour deals in the window but Redknapp is predicting little activity in terms of ingoings and outgoings before Tuesday night's deadline.
"I can't see an awful lot (happening)," said Redknapp, whose team face Wigan on the night the window shuts.
"I will probably watch a game on Sunday but not with a real eye on anyone, although I'm not going to tell you which match."
Of all the targets linked with Spurs, Samba has been the most high-profile, but the club have not made a move for the Congolese defender despite him handing in a transfer request last week.
Part of the reason for that has to be the outstanding form of Younes Kaboul this term.
Kaboul, 26, arrived at Tottenham in 2007 but left a year later to join Redknapp at Portsmouth after failing to settle in at White Hart Lane.
He has been a much-improved player since he returned to Tottenham to link up with Redknapp again two years ago and he is now Redknapp's second-choice centre-half behind club captain Ledley King.
Kaboul was one of the few players to emerge from last night's narrow FA Cup win over Watford with any credit and Redknapp showered huge praise on the powerful centre-back.
"Kaboul has been absolutely terrific. That's why I signed him twice," Redknapp said.
"He didn't have the best time when he was here the first time but he was only a young boy then.
"I took him to Portsmouth. He was terrific there and that's why I really wanted him back.
"He showed last night exactly what qualities he has got. He is terrific defensively. "I haven't really had to work on him, it's more about making him believe in himself.
"I have signed him twice, that shows how much confidence I have in him. He has been a terrific influence for us."
Redknapp will be hoping for a much better performance from his team on Tuesday when they hope to get back to winning ways in the league against Wigan at White Hart Lane.
Redknapp has a number of injury concerns ahead of the match, however.
Gareth Bale is a doubt due to a thigh strain, Aaron Lennon pulled his hamstring last night and Luka Modric has been suffering from sickness.
King is also struggling for fitness and could join Sandro and William Gallas (both calf) on the sidelines for Wigan's visit.
Redknapp, meanwhile, will return to Southwark Crown Court on Monday morning to continue his defence against two charges of tax evasion. The Tottenham manager denies both charges.
The trial is due to end on Friday and Redknapp will leave assistant Kevin Bond in charge of training in his absence, but is expected to attend the Wigan game.
