England vs. Australia Ashes 2013: Major Keys to Australia's Fourth Test Revival

Thanks to some Ian Bell heroics, England recovered a perilous position at 49-3 on day three of the fourth Ashes Test.

Again, Bell showed all the characteristics that a lion should when its back is pressed against the wall, making 105 not out by the close of play on Sunday.

England are on top but Australia will look to some key performers as they look to reduce the series deficit.

Nathan Lyon

On the opening day, no Australian was held in a higher regard than Nathan Lyon, whose four wickets put the Baggy Greens on top.

England will resume on day four on 234/5, and Australia will look to Lyon to polish off the second innings after removing Kevin Pietersen and Jonny Bairstow after tea.

Michael Clarke

Michael Clarke is the class act in the Australian batting line-up and is the only man who averages over 40  in Test cricket.

He will be a pivotal factor in the Aussie run chase and could take the attack to England spinner Graeme Swann.

Chris Rogers

So far this summer, Chris Rogers has failed to post a decent total in both innings.

The 35-year-old has been dismissed for 16 runs or fewer in four of his seven innings thus far, but he registered his first Test century in the first innings at the Riverside and will look to make another good score in the second.
