Former world number one Andy Murray hit the practice court ahead of what could be his final Australian Open appearance on Monday.

Murray dropped a bombshell on Friday, revealing he plans to retire at Wimbledon – where he has won two of his three grand slam titles – should he make it through the Australian Open due to an ongoing hip issue.

The 31-year-old faces 22nd seed Roberto Bautista Agut in the opening round at Melbourne Park, where fans crowded around Court 17 to watch Murray train hours prior to Monday's clash.

Murray – now ranked 229th in the world – is a five-time Australian Open runner-up, with his last appearance in a final on Rod Laver Arena coming in 2016.

Court 17 packed to the rafters for Andy Murray’s practice session.
