I feel sorry for Clarke, he was head and shoulders above everyone else in the match as a batsman. Amla and Smith scored 100s on a much more sedate pitch than Clarke's (which I'd rate comfortably higher than his Lord's hundred and that was a special innings).
I think the management has to take a stance like Strauss and Flower did after their 51 all out against West Indies. It's the nadir, nothing can be worse than 9/21, and the best thing to do would just be to look ahead.
Mark Waugh and more importantly Damien Martyn have lashed out at Australia's batting (the latter specifically at Haddin).
Elsewhere, Pakistan cruise to victory over Sri Lanka by 8 wickets.
