WOW- what an unbelievable upset! Great stuff from England, very good to know that the Aussies are human after all. I reckon a lot of teams might just draw some inspiration from this before the World Cup.
That said, it could also go the other way- while everyone was predicting the end of the Aussie test dynasty after the 2005 Ashes, the Aussies drew from that experience and only ended up drawing 1 test since, winning all the rest. They`ll still be WC favourites, but definately some of the other teams will have taken note.
Also, England are now looking decidedly better WC prospects, and with KP etc. returning, they might just be contenders. Amazing what a couple of weeks can do to a cricket team.
