MELBOURNE:- Australia bowling coach Craig McDermott has boasted that the newly crowned Ashes winners have the most dangerous attack in world cricket as they focus on a fourth straight Test victory against England. Pacemen Mitchell Johnson, Ryan Harris and Peter Siddle supplemented by spinner Nathan Lyon have dominated England's batsmen. Former Test quick McDermott said he expects no changes to the Australia team for the fourth Test. "They've all performed as a unit fantastically well," McDermott said. "We have the best attack in the world at the moment."–AFP
