Spurs beat Cheltenham and Watford to reach this stage of the competition and have a great chance of making a Wembley semi-final as the winners of Wednesday night's clash will face Bolton at home in the last eight.
"It's a great opportunity for us," Redknapp said.
"We are at home tomorrow and have a home draw in next round so we really want to take the opportunity that we have been given.
"I would love to get to the final and to win with Tottenham. It would be great."
