"We'll wait and see what happens," says boss
The Spurs boss is a known admirer of the South African and it is yet to be seen whether he makes a move in January or waits until the summer - when the player's contract runs out - to get his man, but he has indicated an interest in bringing him to White Hart Lane.
As quoted by Sky Sports, Redknapp said: "If he doesn't sign a contract he'll be a great free transfer for someone at the end of the year, if he doesn't stay at Everton.
"He still belongs to Everton, so it's a difficult one.
"They are still trying to keep him. We'll wait and see what happens."
