The Spurs manager has used the competition to blood the highly-regarded young players.
But they will have limited first-team opportunities if the club do not produce the minor miracle necessary against Shamrock Rovers to extend their European adventure.
Redknapp said: "If we make it through we would keep playing the team we've been playing. So going out will be a bit of problem. You've got lads like Andros Townsend, Jake Livermore and Tom Carroll who have done well and it's been good for them. I would like to get them out on loan if we don't qualify."
