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."
He added: "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."
