London: Australia great Glenn McGrath believes the form of England spearhead James Anderson could determine the course of the Ashes. Australia hold the urn but head into Thursday's opening Test at Edgbaston looking for their first series win in England since 2001.

Anderson has been battling to overcome a calf injury but McGrath believes he could have a huge impact on the five-Test series if he stays fit. "On home soil with the Dukes ball, he's the best in the world bowling in those conditions," McGrath told the Sun in an interview.
