What is England's approach with the ball?
Former England captain Nasser Hussain, speaking to Sky Sports...
"What you like to do is look down on a field and see what the planning is. For a large part of yesterday, you looked at Pakistan and didn't know what the plan was.
"Within a few overs there, you can see immediately what the plans are from Stokes and England: We know we're not going to get caught slip like we do at Headingley, so we're going to bowl straight as it's going to be lbw and bowled.
"We also know from yesterday this ball started reverse-swinging after 30 overs - so immediately after every delivery the ball gets thrown to Root, so we have to get the ball reversing.
"When it does that, then Stokes becomes absolutely vital for me as a bowler."
