Should Sri Lanka emulate India in taming the World champions on the bouncy WACA track, the islanders will zoom into top position in three-team event.

Talking of the Perth pitch Lankan skipper Mahela Jayawardene didn’t seem unduly worried about the nature of the square. “I feel the is extra bounce here and all that is in the mind. You have to play with a positive mind if you are to succeed. It's up to us to show what we are capable of and it's going to be a tough game. Yes, it's Perth, but I don't think the wicket has got any demons on it. It's going to be a good batting wicket with little bit of extra bounce. We just need to adjust to the situation,” said Jayawardene.

He also seemed to take some positives from their last win. “We played some average cricket in the first two games, but we bounced back to win. If we win here, we go on top of the table," he said.

The Lankans have a few injury worries to sort out. Jayawardene, who himself is nursing a slight hamstring strain, said: “We want to see how Ishara comes through. He had a quick bowl today and had a little bit of pain and we have to see how further monitor him. He's going to be vital on this wicket," Jayawardene said.  “Chaminda Vaas and Lasith Malinga will share the new ball while Amarasinghe will come in as first change, if fit and will be supported by Farveez Maharoof, the fourth seamer. The six batsmen and five bowlers combination looks sensible. We can play a seventh batsman, but on these wickets, we are better off to have the fifth bowler," the captain added.

Australia, who have been below their par, have a headaches to overcome starting from their skipper’s form. Ricky Ponting’s lean patch has stretched far too long much to the discomfort of the Australians. The home side has effected two changes. James Hopes, who has recovered from hamstring injury, and Brad Hogg will make their return replacing medium pacer Stuart Clark and Brad Haddin. The match will be Adam Gilchrist's last appearance on his adopted home ground and a big send-off is planned.
