World Cup final puts Popes on opposing sides

Football fans around the globe are deciding whether they will support Germany or Argentina in Sunday's World Cup final.

There is even potential for division behind the ancient walls of the Vatican.

And it just so happens that Francis is Argentinian, and Benedict is German.
