Glenn Roeder says directors of football and head coaches must be on the same page if the system is to work well at a club.
Roeder is set to swiftly begin work in earnest after being appointed to the sporting director committee at Sheffield Wednesday last month, where he is expected to act in a director of football capacity.
And he insists communication is key to ensuring a head coach such as Stuart Gray is given a group of players he is happy to work with.
“It can work at any club when the players are good enough that a head coach is given,” Roeder told Talksport.
“The problem is when you’re given players you don’t want to work with and you don’t believe in them like perhaps the head of recruitment or director of football does.
“The biggest clubs in the world – Real Madrid, Barcelona, clubs of that magnitude – the directors of football buy the players that any manager in the world would be delighted to work with. There’s never any dispute.
“The sooner you come down a level or two from clubs like that, you have to have a good working relationship with whoever the head coach is.
“The head coach has got to work with the players on a daily basis so there has to be an understanding between him and the director of football as to who the players are that come in.”
