It's not every year. First one was in 2007, next in 2009, this one wasn't supposed to happen. There was supposed to be a Champions Trophy in West Indies in 2010 after the one in Pakistan in 2008, but the whole Sri Lankan team being fired at happened and teams stopped going to Pakistan, so they scrapped the 2008 tournament and postponed it to 2009. They didn't want a Champions Trophy in consecutive years, but the Windies already had the infrastructure and the whole gig ready, so they made it into a T20 World Cup. From now on, it'll be every 2 years. Next one's in 2012.
He's Australian. He played for Delhi in the IPL before anyone heard of him and he was brilliant. But he didn't get the call-up to the Australian team for the 2009 T20 World Cup, so he played for the Netherlands because his grandmother's dutch or something like that. Then after that, Australia realized their T20 bowling's a bit shit and wanted to bring in Nannes, so he switched sides 6 months back and now plays for them. He's pretty much all Australian. Crazy stat for you, Nannes represented Australia in the World Skiing championships at 23 and started playing cricket only when he was 24 because he wanted to do something different.
I like him a lot, I think he's brilliant.
