Australia captain Pat Cummins insisted all options remained open as he refused to rule out dropping struggling opener David Warner for the finale of the Ashes series.

Left-handed opener Warner has signaled his intention to retire from test duty against Pakistan at his home ground in Sydney next year.

But the 36-year-old may be denied the chance to go out on his own terms after another double failure against longstanding England nemesis Stuart Broad during Australia's three-wicket defeat in the third Ashes test at Headingley, which was completed Sunday.
