McDonald backs under-fire Marsh for the fifth Test

Australia coach remains optimistic about Starc's availability for the Sydney Test, crucial for both teams

Australia head coach Andrew McDonald conceded that Mitchell Marsh has fallen short of expectations with the bat against India but remained optimistic about Mitchell Starc's availability for the pivotal fifth Test in Sydney.

Starc's fitness remains the primary worry for the hosts after the pacer battled through sore ribs from day three of the Boxing Day Test but still managed to bowl effectively, including claiming the prized wicket of Virat Kohli on the final day.

"Any time you get through the game, it's always a good indicator that you've a chance at the next game," McDonald told reporters after the hosts picked up a memorable victory at the MCG to take a 2-1 lead in the series.
