"I will talk to the team about the history of the national team and the key players who have filled their jerseys," said McDouall who admitted the call from the national team had come out of the blue.
"These young players have flown in from all over the world - Holland, Japan, Germany, England, France and Australia - and some of them won't know each other. Unlike a lot of sports, the players' first loyalty in football is to their club rather than their country, so I want to help create a culture around what the national team means."
McDouall plans to write a book on NZ's football history, which started in 1922 when they beat Australia at Carisbrook in Dunedin, the Basin Reserve in Wellington and at Auckland Domain.
"But they weren't the All Whites then ... they wore black."
Already the writer of a cricket book, he has records of the 458 footballers who have represented the country in a full international.
He will speak about Jock Aird who played for Scotland at the 1954 World Cup before emigrating and becoming an NZ international. Another player from that competition was England's Ken Armstrong who also picked up a number of New Zealand caps.
There's Jock Newall who scored 17 goals in 10 internationals and keeper Richard Wilson who went 930-plus minutes without conceding a goal.
He will, of course, also touch on the World Cup teams of 1982 and 2010. The All Whites failed to qualify for this year's World Cup and tomorrow's friendly against South Africa is part of their preparation for the qualifying tournament for the 2018 competition in Russia.
Unfortunately, McDouall, a supporter of English club West Bromwich Albion, won't be able to stay for the game.
"But if I can help build a bit of team spirit, I'll be happy."
