Marc Overmars has quit his post of director of football at Ajax - just three months after being a candidate for the top job at Newcastle.

Overmars said: "I am ashamed. Last week I was confronted with reports about my behaviour and how this has come across to others.

"We are working on something very beautiful here, so this news will also be a blow to everyone who cares about Ajax.
