Australia coach Mickey Arthur says he isn't sure about playing two spinners in the second Test against India in Hyderabad, but concedes that a slow duo may have been a good idea in Chennai, where his side lost by eight wickets.

Arthur pointed out that while spinner Ravi Ashwin took 12 wickets for India on a turning track, the wickets for the Aussies were mostly taken by pace bowlers, so he wasn't sure if two spinners would have made a difference.

The coach said: "That's going to be the million dollar question. It's easy in hindsight having a look at how the wicket ended up, you probably would have liked two spinners on there, however, our quicks took most wickets.

"We didn't get a massive return from spin in this game. I thought James Pattinson was outstanding, so it's a difficult dilemma.

"I think going to Hyderabad we'll have to look at conditions before we make a proper decision. Looking at the way it ended up probably two spinners [would have been good] but our quicks were the most likely out there, so I am not sure which way really."

Arthur was quick to defend Nathan Lyon, saying the spinner would have learned a lot from the humbling experience of going for 215 runs in one innings, and that he had been working hard on his lines and technique ahead of the series.

Arthur said of Lyon: "I think he has learnt from this game that you have got to be really consistent in conditions like this in order to put the batsmen under any sort of pressure, but I think he will grow and he will learn from this game.

"It will be interesting to see how he pulls up after this Test match and in terms of information and preparation and everything he worked extremely hard coming into this Test match. Only he knows how he will approach things if he plays in the next Test match and how that is going to go."

The question then moved onto whether it would be useful to have spinners who turned the ball both into and away from the right-handers, with Arthur saying Lyon's off-spin was handy as it forced a batsman to play the ball, but having left-armer Xavier Doherty would also be a good bet.

Arthur added: "I think on wickets like this balls turning into you are just as effective, because you've actually got to play. You can't leave balls alone. Balls coming into the bat on wickets that have crumbled are almost as tough to play.

"Ideally you want both, and I did a lot of looking at the England series and they used Panesar a lot. You use the left-armer a lot more in the first innings here because you get a lot more control from your left-armer.

"But when the wickets start breaking up, your off-spinner to the right handers becomes dangerous because you've got to keep playing him all the time. Ideally, it would be nice to have the pigeon pair."
