Rafael van der Vaart has revealed he's had his disagreements with Tottenham boss Harry Redknapp.

The attacking midfielder believes the fact he feels comfortable enough to be honest with Redknapp only underlines his capability as a manager.

"When your relationship is good, you can tell somebody the truth," he told the Guardian.

"It's better to do it like this. To go to him and talk about it rather than go behind his back or say something in the newspapers. You always have to be honest.

"You get to a certain point and then you say, 'Listen, I don't like it'. I think it's a good thing and I also go home happy. You are not frustrated."
