Guus Hiddink has revealed he has acted as an adviser to Chelsea since his spell as caretaker manager two years ago as he continues to be linked with a possible return to Stamford Bridge.
The Dutchman took over as caretaker boss in February 2009 following the sacking of Luiz Felipe Scolari and guided the Blues to the FA Cup, combining his role in west London with his duties as Russia manager.
He wrote in his column in De Telegraaf: "It works well with Chelsea. Since I left two years ago I've been advising the club on things concerning the squad."
He added: "Sometimes I become a sounding board.
"It costs me very little time and I can combine it well with my position with Turkey.
"There is no conflict at all."
The 64-year-old, though, is seriously considering accepting a similar role with Ajax after being approached by Johan Cruyff, adding: "He asked me before to work with Ajax to sit on the board.
"In itself it seems to me a great challenge but I am worried about the practicalities although it might be less complex than a role of adviser."
Hiddink was highly popular in west London and with Carlo Ancelotti's future as manager uncertain, the current Turkey boss has been one of a number of names linked with the Blues.
