Pakistan head coach Mickey Arthur has revealed that the team have tweaked their plan in order to quieten the threat of Alastair Cook and Joe Root in the third Test against England at Edgbaston.

The hosts levelled up the four-match series 1-1 with a 330-run win at Old Trafford last week.

Cook scored 105 runs and 76 unbeaten, while Root racked up a total of 254 in the first innings and 71 not out.

"We had a look at Cook and Root again," Arthur told reporters. "We analysed our plans. We see them as a fundamental to England's batting. If we can get into them with the new ball we've got a real good chance."

The third Test gets underway tomorrow.
