The England striker says he has never wanted to leave Spurs and Harry Redknapp has maintained that the striker is not for sale but Defoe's overriding desire is to play and if that is not happening then he may be tempted with a move.
He told Sky Sports News: "At the end of the day it's not a case of me saying I want to go here, I'm not playing, I want to leave the club.
"It's just a case of me playing. I could understand if I was 19, 20 and I had time on my hands but I'm 29 now and, like I've always said, all I want to do is play football. It's as simple as that."
"As it stands I'm a Tottenham player and if I do play against Manchester City I'll be fully committed. I'm sure everyone knows that at the club."
Liverpool's lack of goals have begun costing them points and boss Kenny Dalglish is keen to add to his front line as he pushed for a Champions League spot.
