Completely agree. I have used a few football-related examples when teaching. It has less impact here in the US, because out a class of, say, 100 students you might have just a handful who actually follow football in Europe, even if most are aware it is the number one global sport. A friend of mine (an Arsenal fan) taught a few a courses on globalization, and football is absolutely perfect for that. He once opened class with "any Spurs fans here?". When one student raised his hand my friend frowned, shook his head, and replied "wrong answer." The poor kid was apparently terrified.
And the kid wasn't actually a San Antonio Spurs fan?
