Sir Alex Ferguson believes South Africa has "a lot to offer" and will be equipped to host the World Cup in two years' time.
A number of concerns have been expressed about the nation's ability to complete building work and stage the tournament.
The main focus appears to centre on whether new stadia will be finished in time and whether there will be adequate transport links.
But the Manchester United manager is confident the authorities will rise to the challenge and put on a show for the global football community.
Ferguson said: "South Africa has a lot to offer. Yes they have a job to do in terms of infrastructure.
"But they can manage that because they have major areas to host games in Cape Town, Durban and Johannesburg.
"Johannesburg, which is the biggest platform for the World Cup, is a massive city and area.
"From a professional point of the view, the stadiums at the moment are great. They deserve a chance."
Ferguson has seen a massive change in the South African sporting landscape in the past few years as the country continues to bounce back from years of apartheid and subsequent isolation from the outside world.
"The country is growing - it is a developing country," said the United boss.
"It is also a sporting country. The changes have been phenomenal since Nelson Mandela (who was released from prison in 1990) came back.
"South Africa has got a great future and deserves a chance."
Ferguson believes club football in South Africa is also beginning to develop.
United have had two tough, physical games in the last week against Kaizer Chiefs and Orlando Pirates in the Vodacom Challenge.
The fact that former Dutch star Rudi Krol is now in charge of the Pirates is an indication that coaching standards are also being raised.
United chalked up a 1-0 victory against Krol's side on Tuesday but not without a fight, and Ferguson has nothing but admiration for the man who was in the opposition dug-out.
He said: "He was one of the most fantastic players I ever saw. To me there was Cruyff, who was world class, and then Krol. He was a magnificent player."
Ferguson expects another hard work-out for his side on Saturday, whether it is against the Pirates or Kaizer Chiefs, who play for the chance to face United tonight.
He said: "What you have to realise is that the black South Africans are athletic, tough and quick."
United then move on to Nigeria and a friendly against Portsmouth on Sunday before flying home.
