United will face Tottenham at Old Trafford in the Premier League on Sunday afternoon.
“The problem they'll face is this Tottenham team are regaining momentum after a tricky few weeks - and they don't have the same fear of Old Trafford that they once did, either,” former Spurs midfielder Redknapp wrote on Skysports.com.
“The gap has closed between these two clubs over the last few years. When I went to Tottenham they hadn't won at Old Trafford in I don't know how many years and every time you went there you could see and feel the players were apprehensive about it.
“It's daunting enough as it is to go to Old Trafford, but even more so when you've got a team who don't really feel they can win. Tottenham got so used to getting beaten there.
“But you can see now they go to Old Trafford without the fear they used to. There's a collective belief in the Tottenham camp.”
Tottenham have won their last two competitive matches and are scoring goals for fun at the moment.
The North London outfit got the better of Swansea City 5-0 at White Hart Lane in the Premier League last weekend.
Then on Wednesday evening, Spurs won 3-1 against CSKA Moscow at the Wembley Stadium in London in Champions League Group E.
