Michael Hussey (live cricket online: 11/2 - Top Team Batman bet365) said it was imperative Australia closed out the Commonwealth Bank Series against Sri Lanka "in a professional manner".

Aussie captain Michael Clarke expressed concern at the manner in which his side had opened the door for the tourists to sneak within 15 runs of what appeared to be an unlikely victory at the Gabba on Sunday.

A combination of bad bowling and scintilating knocks from Nuwan Kulasekara (73 from 43 balls) and Upul Tharanga (60 from 67) ensured a gripping finale but it proved too close for comfort for Clarke.

Hussey, who took 4-43, said Australia's bowlers had failed to deliver and admitted they owed their followers a big performance (cricket bets: Australia 1/7 Sri Lanka 9/2 - Commonwealth Bank Series ouright).

"This is a chance to win a series - not all of us have actually won a series in Australia in one-day international cricket," Hussey said.

"So it's very important we actually close out the series in a professional manner."

Hussey said the players were determined not to let Sri Lanka out of their grasp this time around.

He added: "I thought we played three-quarters of the perfect game last night - and hopefully there is a perfect game just around the corner."

Explosive batsman David Warner – who hit 163 from 157 balls - faces a last-minute fitness test on a groin injury before Tuesday's day-nighter.

Vice-captain Shane Watson could return to the opening position, while newcomer Peter Forrest appears likely to return to the starting line-up if Warner is ruled out.
