Spurs legend Terry Venables believes that it was right for the club to axe director of football, Damien Comolli, after a number of high profile mistakes.

"I cannot think of one instance when the idea has been a success," said Venables.

"Jose Mourinho's nose was first put out of joint at Chelsea by the arrival of Frank Arnesen. The appointment of Avram Grant was the final straw.

"Kevin Keegan was tipped over the edge at Newcastle by Dennis Wise and Alan Curbishley resigned as West Ham boss because Gianluca Nani was dictating transfer policy.

"So it was no surprise Harry Redknapp wasn't going to work with Comolli or any other director of football."
