Tottenham boss Harry Redknapp admits he's unhappy with the form of striker Jermain Defoe.

For the defeat to Burnley, Defoe was again substituted in the second half and Redknapp admitted he has been disappointed by the form of the World Cup hopeful.

"I wanted more from him than what he was giving," said Redknapp. "His form's not been so good lately so I've taken him off when he's not played well. It's private between me and him how he's playing."
