Kohli acknowledges folly after selection disaster at Perth

'It's a very tricky decision to make what kind of a bowling option you want to go with or you want to think whether that guy can contribute with the bat as well or not. Eventually you come to one decision and we backed that decision and we went ahead with it. Whether it comes off or not is a different thing.'

India captain Virat Kohli effectively admitted to misreading the pitch at Perth's new stadium after not picking a frontline spinner in a Test match in which off-spinner Nathan Lyon emerged as Australia's trump card.

On the green-tinged pitch the touring side opted for an all-pace attack, drafting in quick Umesh Yadav for injured off-spinner Ravichandran Ashwin. All-rounder Hanuma Vihari, who replaced Rohit Sharma, was India's only slow bowling option.

Kohli said India would have considered playing Ashwin if the spin ace had been fit but was keener to laud Lyon's brilliance for his match-winning figures of 8-106 rather than credit the assistance from the surface.

"It was the pace on the ball Lyon bowled with that got him the wickets," Kohli said after the hosts squared the four-Test series at 1-1 with a 146-run victory.

"We didn't think that we definitely wanted to consider a spinning option on this pitch, especially having a look at the pitch on day one and how we thought it would play on the first three days.

"We thought a fast bowler is going to be more productive and more helpful for us."

India have left-arm spinner Ravindra Jadeja and left-arm wrist spinner Kuldeep Yadav as the other slow bowling options in the squad but preferred speedster Umesh Yadav, who struggled with match figures of 2-139.

Not picking Jadeja, who averages over 32 with the bat from 39 Tests, also robbed India of balance and lengthened their tail with their last four batsmen totalling just 11 runs between them for the match.

"We all know Ashwin or Jadeja have more ability with the bat," Kohli said.

"It's a very tricky decision to make what kind of a bowling option you want to go with or you want to think whether that guy can contribute with the bat as well or not.

"Eventually you come to one decision and we backed that decision and we went ahead with it. Whether it comes off or not is a different thing.

"But we were totally convinced as a team that is our best combination to go with and the batsmen have to take responsibility."

When asked why Umesh Yadav was picked ahead of Bhuvneshwar Kumar despite ample grass on the pitch, he replied, "Bhuvi hasn't played a lot of four-day cricket recently and Umesh took ten wickets in his last Test (against West Indies) and was in good bowling rhythm. So that was the reason behind picking Umesh over Bhuvi."
