Prior to open as England bat

Jonathan Trott and Ian Bell

Bangladesh won the toss and asked England to bat first, as their crucial Group B clash prepared to get underway in front of a rapt full house at the newly renovated Chittagong stadium. After their catastrophic performance against West Indies in Dhaka, Bangladesh's captain Shakib Al Hasan chose not to risk a repeat scenario of their 58 all out in that match, although his opposite number Andrew Strauss admitted he would also have bowled first given the chance, on a flat and dry wicket that promises a tough day for strokemakers on both sides.

After a tight-lipped build-up to the match, England finally revealed their reshuffled hand in the absence of the injured Kevin Pietersen and Stuart Broad. Matt Prior, who opened the batting in Australia last month, has been shunted back up the order in preference to Ian Bell and Ravi Bopara, while Ajmal Shahzad, who made his ODI debut on the same ground last year, is recalled ahead of Chris Tremlett.

Michael Yardy, who struggled in spin-friendly conditions in Chennai last week, makes way for Paul Collingwood, whose offcutters could prove useful on a low surface, while Eoin Morgan, who was forced to withdraw from the squad last month with a broken finger, will slot straight back into his favoured No. 5 position, having answered Andy Flower's SOS and linked up with the squad this week. He may not be fully acclimatised just yet, but Bangladesh will remember his match-winning feats last year, in particular his nerveless hundred at Dhaka.

Bangladesh have made a solitary change to their team, with the ever-underachieving Mohammad Ashraful omitted in favour of the combative offspinning allrounder Mahmudullah, who scored two fifties in the Tests against England last year. Despite the collective failure of their batsmen, the rest of the line-up have been trusted to make amends for their shortcomings against West Indies.

Thanks to England's remarkable victory over South Africa in Chennai, this contest is no longer make-or-break for them - a mishap here, and they will still get another chance to qualify in their final group fixture against West Indies next week. For Bangladesh, however, it is now or never. The euphoria of their victory over Ireland has dissipated, and they know that a failure here will end their chances of progressing to a home quarter-final in Mirpur.
