The Spurs boss is confident that when he gets key players back from injury that performances and results will improve and the possibility of a top-four finish will be much more achievable.
"I still think we can get into the Champions League. When Modric and Lennon are fit and Defoe is available again after his suspension, we have a terrific team," Redknapp said.
"People will question us getting into the Champions League but it's nice proving people wrong in life.
"I'm not giving up on the Champions League, it's not impossible, it's all about a couple of points."
