In South Korea, they call it the 2-0 necktie. Head coach Huh Jung-moo wore it when the republic shut out Greece in its opening World Cup match.

Before the next game, President Lee Myung-Bak was wearing the red tie with black stripes during official meetings.

The president, a big soccer fan, might break out the tie at G20 meetings Saturday, when South Korea plays Uruguay.

Lee is just one of six leaders who has to balance the fate of the world’s economy with the World Cup this weekend.

Beatrice Fenelon of the Summit Management Office said organizers are very conscious of the tournament. “Rest assured. Leaders, delegates and media will be able to follow the game during the summits,” she said.

So if you hear a terrified gasp from Angela Merkel at the Metro Toronto Convention Centre Sunday, chances are England just scored against her beloved team. If Germany strikes first, tensions could escalate between the chancellor and British Prime Minister David Cameron.

Before she left Germany Thursday, Merkel told reporters she will focus on the summit, but her thoughts will be with the team Sunday.

The U.S. consulate was not able to say where the president will be watching the match against Ghana. His schedule has him en route to Toronto Saturday afternoon.

Likewise, Argentina President Cristina Fernandez de Kirchner and Mexican President Felipe Calderon will probably be busy when their teams square off Sunday.
