Redknapp, however, says that he is simply making the most of an injury-hit squad, as well as having one eye on Sunday's visit of Liverpool in the League.
"It's not a case of prioritising a game, it's just [using] what I have got," he said.
"I couldn't bring players out here, play them on Thursday night and play the same group against Liverpool.
"If I get a few injuries I have no back-up. I have nine senior, very, very good players who are injured."
The White Hart Lane club are joined by Rubin Kazan and Shamrock Rovers in Group A of the competition.
