Manchester United manager Sir Alex Ferguson has backed Harry Redknapp as "the best man" for the England job.
Tottenham boss Redknapp is being widely tipped as the replacement for Fabio Capello, who resigned as England manager on Wednesday evening.
"There is no doubt Harry Redknapp is the best man," Ferguson said.
"The press have decided. Harry is the best man.
"He has the experience and personality and the knowledge of the game. He has changed the fortunes of every club he has been at.
"He is the right choice.
"You should try to get the best man with the best qualities. A young manager has no chance."
Tottenham are in the hunt for their first league title since 1961 and there has been a suggestion Redknapp could take the England job part-time.
But, Ferguson who took on the Scotland job for the 1986 World Cup while Aberdeen manager following the death of Jock Stein, cautioned against that approach.
He added: "I tried it myself with Scotland in Mexico. I found it very difficult."
Mandaric also believes there is no better candidate to manage England than Redknapp.
Sheffield Wednesday chairman Mandaric and Tottenham manager Redknapp were together at Portsmouth and Mandaric believes his former colleague is the right man for the job.
Mandaric and Redknapp were both cleared of tax evasion charges relating to their time at Portsmouth on Wednesday, the same day Capello resigned as England manager over the Football Association's decision to take the national captaincy off Chelsea defender John Terry.
Mandaric has now backed his friend Redknapp to become the next manager of England.
He told Sky Sports News: "I don't think there is a better man than Harry Redknapp to take over England.
"I possibly shouldn't say that because it is not my job to talk about managers who are employees and are very happy with their job.
"I want England to be successful because I am a big part of English football."
