Tottenham Hotspur boss Harry Redknapp believes that it can be "difficult" for a manager to work with a director of football.
Damien Comolli, who fulfilled the role at Liverpool, recently left Anfield by mutual consent but Redknapp does expect Kenny Dalglish to suffer as a result.
"It can be difficult but it depends on the relationship between the manager and the director of football," Redknapp told talkSPORT.
"If you're both on the same wavelength and you want the same thing then I don't think it is such a problem. I couldn't work under those circumstances. If someone is choosing your players and they're no good then you are going to get the sack.
"The manager picks the team, trains the players every day and you've got to be the one that is making the big decisions. If your chairman is okay to work with then you don't need that middle man there."
Comolli was previously director of football at Spurs and was involved in the deal that brought Gareth Bale to White Hart Lane.
