With the Ashes in the balance at one Test apiece, both England and Australia will be looking to seize control of the series when they take to the field at Edgbaston today.
England captain Alastair Cook has said he's ready to banish the nightmare of Lord's two weeks ago, where England suffered a painful 405-run defeat. But to do so he and his fellow batsmen in England's top order must produce a far more assured display.
But where will the runs come from?
As demonstrated in the graph below - which breaks down key batting stats for both sides - England's top order has the pedigree, history and experience to put numbers on the board. There's only one problem: So do Australia.
Looking at the averages through the order, Australia seem to have the stronger opening lineup
Jonny Bairstow has been drafted in to replace Gary Ballance while Ian Bell and Joe Root have both been shunted up the batting order. Steven Finn has also been brought into England's XI in the place of Mark Wood.
Meanwhile Australia's top order of David Warner, Chris Rogers and Steve Smith looks set to remain unchanged and wicketkeeper Peter Nevill is set to keep his place despite Brad Haddin's return to duty.
