Guus Hiddink has announced that he is to retire at the end of the season.
The 66-year-old currently manages Russian side Anzhi Makhachkala.
The Dutchman told De Telegraaf: "It was not my intention to stay very long when I joined this club.
"I'm basically going to stop at the end of the season. At 66 years old I think I've nearly had enough.
"I don't know what I'll do. Maybe I'll be an advisor or supervisor to young players or coaches. I want to teach people how to handle certain issues in football or how they can plot their career path. That sounds interesting. I will not disappear into a black hole."
Hiddink's managerial career has spanned 30 years, including stints at PSV Eindhoven, Real Madrid and Chelsea, as well as national roles for South Korea, Australia and Russia.
