Pakistan coach Waqar Younis has concerns over his team's batting over the longer one-day format ahead of the three-match One Day International series against Australia.

Pakistan limped to 96 for nine in the one-off Twenty20 against Australia in Dubai on Sunday with debutant Saad Nasim the highest scorer with 25.

Australia knocked off the required runs with six overs left to spare and Younis is now questioning the strength in his top order as only two of the top eight reached double figures, with Umar Amin and Sohaib Maqsood recording ducks.

"Batting, we didn't really put enough runs on the board," Younis told ESPN Cricinfo ahead of the series being held in the United Arab Emirates, with the first clash on Tuesday.

"Losing early wickets, it was not easy after that. And full credit to the Australians, they bowled well, they bowled to the plan and they came out good. I think there was nothing wrong with the pitch, it just spun a little more than usual.

"The major focus for us is how are we going to deal with 50 overs? We have to make sure that we bat 50 overs. It was disappointing what happened today."

Umar Akmal was one of the batsmen to under perform as his poor run of form continued with one from five balls.

"That's not only a worrying sign for U (Umar) but for us also," Younis said.

"We have to really sit down and think hard about his batting, and his wicketkeeping also. We speak about his talent. He hasn't really delivered. We have to really speak to him and maybe try different things with him."

Australia all-rounder Glenn Maxwell, who claimed three for 13 in the Twenty20 match, is aiming to back up that win by piling the pressure on Pakistan and dominating the series.

"To start a series like that where it's a really dominating win with six overs left is a great way to start a tour," he said.

"If you can keep your foot on the throat the whole way through the tour and basically stay on the opposition the whole way through, it just shows what you're really here to do.

"Going back to the India tour where India just basically stood on us the whole way through that series and it was tough to come back from. Hopefully we can do that to Pakistan and go home with six wins."
