'Crawley a real test for the Stokes-McCullum England era'

England opener Zak Crawley's Test match struggles continued on day two of the Edgbaston Test against India as he recorded his ninth single-figure score in 11 Test innings.

The 24-year-old Kent right-hander has received the public backing of head coach Brendon McCullum and captain Ben Stokes but, after his latest failure with the bat, Sky Sports pundits and former England captains Nasser Hussain and Michael Atherton discussed how long they can persevere with him and what needs to change for him to succeed.

"We heard Ravi Shastri talking about how Rohit Sharma and KL Rahul spent hours and hours in Durham last summer, in the nets against the Dukes ball, leaving the ball outside off stump. In England, the leave becomes a really important stroke - but does it under McCullum and Stokes?
