Melbourne - Australia vice-captain Brad Haddin says motivation won't be a problem for the hosts in the fourth test against England starting on Thursday, though they've already reclaimed the Ashes and hold a 3-0 lead in the five-Test series.
Haddin said Australia is determined to press for the 5-0 series sweep which will lift them from fifth to third on world Test rankings and to further avenge its recent defeats at England's hands.
"I've been on the end of a few hidings from England so from my point of view it's not that hard at all. We'll play this game in the same spirit and with the same fight we've shown throughout my whole Test career."
Haddin said Australia was already aiming not just at the No 3 ranking, but to the summit.
"We want to challenge ourselves to be the best cricketers we can be as a group and we hope that end result is to be No 1 in the world," he said.
But Haddin said the real Test of Australia's aspiration to become No 1 will likely come in the tour of South Africa.
"That's a true test of where we're at," he said. "You want to play the best and you're not going to get to No 1 hiding away and not playing the best," he said.
"That's a challenge put to the group and we're pretty hungry to achieve that."
Opening batsman David Warner has scored two centuries and two half centuries in the three Tests against England so far and said he hoped his form would continue.
"I don't need much for Christmas apart from coming out here and scoring runs for the team and having a Boxing Day victory to go 4-0," Warner said.
"I know sometimes I can get too far ahead of myself but I've got to keep my feet on the ground and keep working as hard as I can.
"It's good to be on a high; I've never been on a roll like this before but I've got to work out the best way to keep scoring runs."
