Difference between Australia's and England's sides is.. For England to win any game they need their whole team to fire up and perform well.. For Australia to win they only need 1 batsman and 1 Bowler to go well..
At the moment though, besides that Ponting century Australia's batting is very stale. Hayden has seemed to lost the plot, the bowling isn't much better. With McGrath carrying the injury all the pressure is on Warne's shoulders. But he alone could bowl England out on a shit day.
The games have been entertaining though. I give my props to England for coming back after that 1st test onslaught. If they don't win the ashes on their home soil however, there's no way they'll win it for along time. Because as if England could possibly win back here in Australia LOL..
peace.
