Geoffrey Boycott rates Alastair Cook as 'world's best opening batsman'

Former England batsman Geoffrey Boycott says if he had to pick a team of the world's best players, Alastair Cook would open the batting.

A superb double century from Cook saw England to 569-8, a lead of 46 runs, at the end of day four of the first Test against Pakistan.

Cook batted for 836 minutes in Abu Dhabi for his 263 - the third-longest innings by time in Test history, and the longest ever by an Englishman.
