David Warner's 166 leads Australia to top of CWC19 standings
Aaron Finch and Warner continued their excellent form as a partnership at the top of the order by putting on 121 for the first wicket.
The introduction of part-time seamer Soumya Sarkar saw to the removal of the Australia skipper for 53, but with Usman Khawaja as his batting colleague, Warner continued to motor along, bringing up his second century of the tournament off 110 balls.

The opener seemed to go up a gear after reaching his ton, taking the attack to the bowlers as he went from 100 to 150 in just 29 balls. Meanwhile, Khawaja continued to tick along nicely, getting to his own landmark of a first World Cup half-century from 50 balls.
Warner went on to reach the highest individual score of the tournament – and while his stay ended in the 45th over, a blistering 10-ball 32 from Glenn Maxwell proved more than useful as the Australians finished on 381/5.
A mix-up between Soumya and Tamim Iqbal, leading to the dismissal of the former, saw to an early disruption to the Bangladesh run-chase. Shakib Al Hasan, the man of the moment, arrived to steady the ship with Tamim, but Marcus Stoinis – making his return from injury – struck in the 19th over to remove Bangladesh’s talismanic all-rounder.

The wickets of Tamim and Liton Das followed but then began a comeback led by Mahmudullah and Mushfiqur Rahim. The pair put on 127 for the fifth wicket, every run greeted by a chorus of cheers from the heavy contingent of Bangladesh fans at Trent Bridge. And while Australia's bowlers held their nerve to help their side to their fifth win of the tournament, a century for Mushfiqur was a moment to savour for the sea of green shirts in Nottingham.
