With Defoe now fit, Redknapp needs to decide how he juggles his options.
The England man said: "You're going to have to ask the manager that. I don't know. At the end of the day there's a lot of games. We're in the knockout stages of the Champions League, there's the League and the FA Cup is coming up, so a lot of games to be played.
"We've still got Pav, Robbie Keane, a lot of players, and it's a good thing because it keeps you on your toes because you know that when you do play, especially as a forward, you've got to get your goals and make sure your sharp and bright and play well to stay in the team."
