I think Australia will loose 4 - 5 wkts in those 30 overs bowled by Vaas, Malinga and Murali coz they Aussies have not faced them in Carribean pitches ( Hats off to Lankan planning) and a great reason for result will be affected how other supporting bowlers perform
But one thing is sure , It will not be a high scoring match because both teams have excellent bowling well supported by outstanding fielding skills and Aussies may loose here as I have already pointed out that their lower middle order and tail enders have not got the batting practice through out the tournament and there is possibility that they may CRUMBLE???? is it not??
