Andrew Strauss believes England are developing the battling qualities that will serve them well in their bid to retain the Ashes after they thrashed Pakistan by 354 runs in the first Test.

Victory, achieved with a more than a day to spare at Trent Bridge on Sunday, was ultimately crushing with Pakistan bowled out for 80 - their lowest Test score against England - in pursuit of what would have been a new world record fourth innings victory total of 435.
