Also, regarding all this talk of complacency:
With all due respect, I frankly cannot see this Australian side being complacent for a WC final (its rather hard for me to imagine Ponting waking up on the morning of the final thinking "lets take it easy today"). Simply not going to happen.
Moreover, this match is the last hurrah for the old guard. It is probably Gilly's last major odi, and it certainly is Mcgrath's last odi. Again, no reason for complacency, in fact all the more reason for intensity and focus and a raising of performances.
It may be that Australia will have a bad day, they are due for one, but the odds are against it when we consider that with everything at stake, Australia will be doing their best not to have a bad day, and rather to have a very good day.
I doubt Sri Lanka will win it, but I do hope for a good game - even if I doubt a close one.
(It will take something truly exceptional for the Lankans to take this one out)
