Port Vale chairman Bill Bratt has promised to cast the net as wide as possible to find a new manager, following the departure of Martin Foyle last month.
Former Valiants striker Foyle paid the price for a disappointing start to the season in late September.
But, although Bratt claims current caretaker-manager Dean Glover is in the frame for the job on a permanent basis, the Vale supremo is planning to consider applications from overseas candidates.
"Interviews will start this week with candidates for the manager's position at the club," he told the club's official website.
"However, the board has decided to cast the net even further by advertising the job.
"All options are being considered including the possibility of appointing an overseas manager or reorganising the managerial structure of the club to accommodate a player-coach.
"We would like to make it clear that caretaker-manager Dean Glover is one of the candidates and has the board's full support in the interim period.
"Since Dean took charge performances have improved, despite of the events at Morecombe (2-2 draw) when we feel the manager was let down by certain players.
"Dean has been given the go-ahead to bring in new players to strengthen the squad."
