The White Hart Lane side currently sit in second place in Group A, three points behind Inter. However, they need at least a draw to ensure that they remain in pole position to qualify for the knockout stages behind their Italian opponents.
The other teams in the group, Werder Bremen and FC Twente, also play on Tuesday and a win for either side, coupled with a Tottenham defeat, would leapfrog them above Redknapp’s side; something he is well aware of.
"It's a tight group and we need to get something from this game," Redknapp told the club’s official website.
"It's a very important match, especially with Werder Bremen playing Twente. If one of those teams manage to win, we'll need to get points on the board as well.
"Inter have real quality, they are champions of Italy as well as Champions League holders. It's a very tough game, but I fancy us at home, in front of our fans.
"We have to set a high tempo, play the way we want to play and I think it will be a great night's football."
The Tottenham manager believes that his side will be more confident going in to Tuesday's game, after a Gareth Bale hat-trick restored some respectability to the scoreline in their previous match against Inter.
Spurs were 4-0 down and played much of the game with just 10 men after a calamitous first half in the San Siro just under a fortnight ago. However, Redknapp believes their subsequent recovery will prove to be important.
"The goals were important not just to give the players belief, but if we'd have come away from there with it looking as bad as could have, it would have been very difficult," he said.
"There were parts of the game where I felt we could cause them some problems but we just got off to that horrific start. Everything that could have gone wrong did go wrong early in the game and that made it difficult.
"So to come back and for Gareth to score such a fantastic hat-trick to give us some respectability in the scoreline was very important."
