A few years ago, I met Franz Beckenbauer and asked him something I'd wondered for two decades. Beckenbauer is a German legend and the only man to lift the World Cup as captain (1974) and coach (1990).
He was also the coach in 1986, when West Germany lost 3-2 to a Diego Maradona-inspired Argentina at the Azteca Stadium. That day, Beckenbauer chose to use Lothar Matthaus, one of his best attacking midfielders, to man-mark Maradona, which, while it neutralised El Diego somewhat, also effectively took the German linchpin out of the game.
"Did you regret that decision?" I asked Beckenbauer, in Auckland to attend the 2008 Fifa Under-17 Women's World Cup final.
"Yes, of course," Der Kaiser said with a smile. "But everything is always easy afterwards. At the time, it seemed like the best plan."
Twenty-eight years on, and tomorrow, Germany will need to stop another Argentine superstar, Lionel Messi. The four-time world player of the year has been superb at this World Cup, after failing to shine in the 2006 and 2010 editions, and is the undoubted trump card for the South Americans.
