But the former Spurs chief admits it would be difficult to persuade the 29-year-old to drop down to the Championship.
"He'd be a great loan, that's for sure," said Redknapp.
"I don't know what will happen with him. He's a good player but it's up to Tottenham, they have lots of good players.
"He can't go on loan in the Premier League, he can only go into the Championship but whether he'd want to do that - it would be difficult I think."
