Former Australia cricketer Ian Chappell believes captains were partly to blame for the lack of leg-spin options in the current Test team, saying skippers are yet to understand how wrist-spin bowling works in the longest format of the game. In the last 10 years, off-spinner Nathan Lyon has led Australia’s spin attack in Tests. But his series-ending calf injury during the second Ashes Test meant Australia had to use young off-spinner Todd Murphy in two of the remaining three games. It deprived Australia of control from the other end as England came back from 2-0 down to end the series at 2-2.
