With the likes of Zlatan Ibrahimovic, Alexandre Pato, and Robinho among the Milan ranks, Redknapp would be forgiven for ordering his remaining players available to play cautiously, but he insists that is not an option.
"Attacking football is what got us here in the first place. We have had a go all through this competition so we will have a right go again at San Siro," said Redknapp.
"We can score here. I don't want to concede bags of goals for sure. We can't afford to make the same mistakes and can't start like that again but as far as shutting up shop goes it's a non-starter because we don't have the players here."
Gareth Bale's withdrawal with a back injury is a big blow for Tottenham given his inspirational role in their narrow 4-3 defeat to Inter Milan at the San Siro four months ago and in the 3-1 win at White Hart Lane in the reverse fixture in November.
Niko Kranjcar has played well in Bale's absence, scoring two in his last two games.
Redknapp is glad the Croatia midfielder decided to turn down the chance to leave White Hart Lane last month and is convinced he will be put in a good performance this evening.
He said: "The most difficult part of this job is leaving people out of the team but to be fair Niko just got on with it, kept working hard and got back in. Niko genuinely is a great lad. He never came in to tell me he didn't want to travel away from home or anything."
Serie A leaders Milan may be without Gianluca Zambrotta, Massimo Ambrosini, Andrea Pirlo and Filippo Inzaghi for tonight's game but have been buoyed by Saturday's 4-0 win against Parma and are confident of progressing thanks to their wealth of experience in Europe's premier club competition.
Striker Zlatan Ibrahimovic said: "We have a big advantage in that we have many players who have won the Champions League a couple of times, they have lots of experience that gives you calm and tranquility in the team."
