Redknapp had lined up the England Under-21 striker as a deadline-day loan signing to replace Andrew Johnson before his proposed move to Crystal Palace fell through.
He said: "I was going to take Harry on the deadline. I was going to take him that night when AJ looked like he was going to Palace.
"Now, I don't know. Harry's probably the third choice at Spurs now. Whether they'll still loan him, I don't know. They might do.
"Andy Johnson missed all of last season - is he going to stay fit? Bobby Zamora's had problems too.
"That is the only area. Everywhere else I'm very happy with."
Is there anyone in our squad he doesn't want to take on loan? Actually it could be a good motivator, play well or you'll end up at QPR!- markofaspur
