I'd have to agree with the Baron, it doesn't look good for the Aussies
Could be 2005 all over again.
I think one of the things with Aussie was they had arguably the best test and one day sides for nearly a decade. The public perception is that the Aussie side are still of the same calibre as that of ten years ago - a side that was the perfect storm of a perfect collection of exceptional talent all at the same time, one of those once in a century happenings. A lot of those special players have retired and now things are at a more even keel.
I honestly think that the crux of the matter is Aussie is lacking the bowling attack (either pace or spin) to do damage to the England order, and that might be the biggest factor in this series. When you have batsmen of the class of Cook and Pietersen you have to have the heavy artillery to deal with that.
