Veteran Australian opener Usman Khawaja is expected to address his Test future ahead of the fifth Ashes Test in Sydney. The 39-year-old has faced a challenging period in his career, with recent batting averages below his usual standard. Khawaja's performance in the current Ashes series has been modest, and he has also experienced some disruption due to injury and batting order changes. Former players have advised him to control his own career decisions.
