Wednesday's goalless draw with AC Milan completed a 1-0 aggregate win after Peter Crouch's goal in the San Siro three weeks ago - and set up the possibility of a last-eight clash with Barcelona, conquerors of Spurs' local rivals Arsenal on Tuesday.
Redknapp admits Barca are the team to beat, but will await the outcome of the draw with eager anticipation.
"Barcelona were amazing the other night," he said. "Arsenal had a man sent off but to outpass Arsenal - who are as good as any team in the Premier League and were made to look so ordinary - (Barca) are as good a team as I've seen in my time in football, they're the team to beat for anybody.
"We're in the last eight and we look forward to the next round when it comes up. You can't pick who you draw - we were in the toughest group but we won that.
"They'll be two fantastic games, whoever we draw."
