Michael Clarke insists he is choosing to ignore Sri Lanka skipper Mahela Jayawardene's comments that the Australian bowling attack is under strength.

The teams are set to clash in Perth on Friday in the tri-series tournament, but Clarke says he is not bothered by opposition comments and chooses to do his talking on the pitch.

"That's Mahela's opinion, he's a very good player and played against a lot of opposition teams, so he feels that way, we just have to make sure we play some really good cricket, whether that be with the bat or the ball," Clarke said.

"I'm not really concerned about the opposition right now, whether that be India or Sri Lanka. There's a lot of areas of our game that we've been working on as a one-day team, and that'll be our focus at training again."

Australia enjoyed a winning start to the ODI tournament after defeating India by 65 runs with the assistance of the Duckworth/Lewis method, but Clarke knows matches will get tougher as the series continues.

"We will be tested as a team all around the world. It's been a really good start to the summer winning the Test series, but you are expected to perform in your own backyard, it's now going to be a test to see how we go when we play overseas," Clarke said.

The 30-year-old added that the team is fully prepared to face the Sri Lankans despite not watching their opponents' four-wicket defeat to India on Wednesday.

"I didn't see one ball," admitted Clarke.

"I was asking on Twitter how I can watch the game, but unfortunately we don't have Gem (General Entertainment and Movies, an Australian television channel) in our hotel.

"So I was getting the scores off Twitter but didn't see one ball unfortunately. We looked at a lot of footage yesterday of the Sri Lankan team, so everyone in our change room knows the opposition, knows their strengths and weaknesses and what we need to do to beat them."
