Who is the 5th bowling option? Or has Australia just accepted that they don't have one in not selecting Mitchell Marsh?
I presume Head/Finch will trundle out a few overs if needed.
Realistically that's all you need as a fifth bowling option in tests, just a few overs here and there.
Well, that's all Marsh ever did. Never bowled more than 18 overs. Tends to bowl less than 10.
India have never lost a match when Kohli wins the toss FWIW
