Nottingham: At the risk of sounding offensive, the 2015 Investec Ashes has been schizophrenic with both teams riding rollercoaster of form through the first three Tests. After England wiped the floor with the Aussies at Cardiff, they were made to relive the nightmares of 2013-14 at Lord's but then romped home in under three days at Birmingham. With the fourth Test at Trent Bridge beginning on Thursday, only the most inveterate of gamblers would venture a guess at the outcome of the contest with both teams swinging wildly from the sublime to the ridiculous.

Steven Finn recalled in to the England XI at Edgbaston after a gap of two years, shot through the powderpuff Aussie batting lineup, will be expected to share the focus of leading the bowling attack with Stuart Broad, in the absence of Jimmy Anderson who has been sidelined by a side strain. Australians will be hoping that Anderson's side is the gift from the gods that England received in 2005 Glenn McGrath's rolled ankle in Edgbaston that turned the tide in an epic Ashes series.
