Queens Park Rangers boss Harry Redknapp believes that directors of football can undermine the manager's role at a club.
The 67-year-old refused to work under the position during his tenure at Tottenham Hotspur due to his strong feelings about the methods of player recruitment, which saw Damien Comolli removed from the role by the club in 2008.
Redknapp told the Evening Standard: "It totally undermines your role as manager if you're not picking the players. It's a joke really that you are expected to work with someone else's players.
"It's all very well someone recommending players to you but when they don't work out, it's your head on the block.
"To expect me to work with players someone else has decided I want is a nonsense. I want to make my own decisions and rightfully so. If things don't work out fine, I'm responsible for that. But why should I be accountable for someone else's mistakes?"
QPR are currently 19th in the Premier League after 11 games this season.
