Australia all-rounder Shane Watson has suggested that Trevor Bayliss could give England an advantage in The Ashes with his knowledge of the tourists.
England coach Bayliss has worked with a number of the touring Australians, including Michael Clarke and Steve Smith, during his time in charge of New South Wales and Watson expects him to have a big impact.
"He knows a lot of us very well," Watson told reporters. "He'll have these ideas about how he can try to expose our team. But we know that if we are at our best we will be very hard to beat.
"The edge will be the inside information he will have."
The first Test gets underway in Cardiff next Wednesday.
