Australian captain Michael Clarke says he is considering ignoring two of his own golden rules for the third Test against India at Perth's WACA Ground, starting Friday. Both teams are considering playing four fast bowlers in the match, with the WACA pitch still boasting a healthy covering of grass and a distinctive green tinge when Clarke inspected it Thursday afternoon. With the luxury of a 2-0 series lead after emphatic wins in Melbourne and Sydney, Clarke said he was considering going for broke against the Indians, not only by using four seamers, but by bowling first if he wins the toss. “I really find it hard to bowl first if I win the toss no matter what the conditions are like,” he said. “And I find it really hard to leave a spinner out of my team no matter what conditions are like. “But in saying that you need to do whatever is best to win the game. The conditions are obviously going to suit fast bowling, especially on day one. I need to assess conditions and make a couple of very smart decisions.” Like the Indians, Clarke said the home side would not settle on their final 11 until a final look at the pitch on the morning of the match. He hinted that paceman Ryan Harris was certain to return, to replace the injured James Pattinson, leaving spinner Nathan Lyon and young left-arm quick Mitchell Starc vying for the final spot in the team. He said any perceived Indian batting frailties, with the tourists yet to notch a century in the series, would not influence selection. “It's about working out what the best attack is to win the Test match,” he said. “I've seen India be successful against fast bowling and spin bowling, so we won't pick the attack for that, it will be about the conditions.” Clarke said Australia's inexperienced top three was not a concern, although India has identified it as a weakness in the home side. India is already certain to lose second spot in the ICC Test rankings, but Dhoni said they were desperate to avoid a repeat of last year's 4-0 whitewash in England. “A lot depends on how it looks before the start of the game,” Dhoni said of the pitch, hinting that spinner Ravi Ashwin could miss the match. “Our bowling will be structured depending on the wicket.” If India go for an all-pace attack, the obvious replacement for Ashwin is 27-year-old medium-pacer Vinay Kumar, who would be making his Test debut, but has played 15 One-Day Internationals. Dhoni may quit Tests Mahendra Singh Dhoni has hinted he will quit Test cricket if he decides to lead India in its World Cup defense in Australia and New Zealand in 2015. “Well if I want to see the 2015 World Cup in, I'll have to retire from one of the formats,” he said.
