Pace bowler Mitchell Starc is likely to hold his spot despite failing to make a breakthrough in the First Test in Chennai where India claimed an eight-wicket win on Tuesday.
Offspinner Nathan Lyon, who copped a hammering from India's batsmen and returned figures of 3-215 and 1-29, is also believed to have held his spot despite a push from back-up spinner Xavier Doherty to win a recall at the expense of either a paceman or Lyon.
Clarke spoke to reporters before training on Friday but said selection had yet to be finalised.
"Those suggestions (in the media regarding an unchanged side) would be incorrect because we haven't picked the XI yet," Clarke said.
"We pick it today at training and I will probably tell the boys after training.
"There is a consideration of playing an extra spinner. We're looking at how we are going to take 20 wickets and how we are going to score enough runs.
"Again I don't want to speculate because I want to speak with with Mickey and John (coach and selector Mickey Arthur and national chairman of selectors John Inverarity).
"There could be no changes but there could be as well."
Clarke said the Hyderabad pitch looked very dry.
India's three-pronged spin attack claimed 20 wickets in Chennai and the home side are expected to stick with their strength in the second Test.
"I'd be very surprised if India played any less spin put it that way. Looking at it yesterday it looked like a day-three or day-four pitch," Clarke said.
Likely Australia team: Michael Clarke (capt), Ed Cowan, David Warner, Phil Hughes, Shane Watson, Matthew Wade, Moises Henriques, Peter Siddle, Mitchell Starc, James Pattinson, Nathan Lyon.
