New Zealand captain Brendon McCullum has told his side that they have to improve, after they struggled with the bat against Scotland today.

The World Cup hosts were set a target of 142, but they lost seven wickets on their way to a narrow three-wicket win, and McCullum insists that they must do better against England on Friday.

He told reporters: "It was a tough one. Credit to Scotland for the way they hung in there. That total was always going to be challenging on a surface like that where it was nibbling about. As a pair we've seen how effective Trent Boult and Tim Southee can be and they were outstanding.

"It was a really good performance with the ball. With the bat, we showed glimpses but we have to improve. England will be a challenge. they're hurting, they'll be tough to beat and we'll have to play incredibly well."

New Zealand have won both their games so far.
