In-form Australia batsman David Warner said the pressure is on all his team-mates to perform in order to keep their spot in the side ahead of the Boxing Day Test against West Indies.
The Windies proved meek opposition in the first Test in Hobart, as the Aussies embarrassed the tourists by an innings and 212 runs.
But Warner insisted there is no diminished feeling heading into another Boxing Day test, with plenty of internal pressure to perform.
Joe Burns' position as opener in particular has come under scrutiny after failing to build on a solid first Test against New Zealand in November, scoring just 98 runs in five Test innings since.
"I think there way he started in the first Test against New Zealand was fantastic and he's working very hard in the nets to try and get his game back to where it was in those first two innings," Warner told reporters in Melbourne on Wednesday.
"Batting together has been fantastic, but that's the nature of the game and you're not scoring as many runs as the selectors like they will or won't pick you.
"It's a tough decision for selectors and it's in their hands."
Warner refused to speculate on who he thought would open the batting on Boxing Day, but said the depth of talent available to selectors was positive.
"It's like the bowlers, it's a time where the batters have to keep scoring runs and if you don't you won't get selected," Warner said.
"We've seen our bowling stocks, we've had a few injuries and a few retirees and now the bowlers have come in and out as well.
"We're all mates. Either way you're going to replace a mate or your mate is going to be there at the other end or you're going to have to try and knock his position off.
"We wish everyone the best and we all play to win. You don't go out there and hope your mate doesn't score runs so you make the team."
Warner said with the number one Test ranking in Australia's sights the Aussies had to do a professional job against a struggling West Indies, insisting playing Boxing Day would remain a special occasion.
"From our point of view, it looked like [West Indies] were going through the motion when we were batting on that day when we batted big, but it's a new game, it's Boxing Day and we're all fired up," Warner said.
"As a kid growing up, just playing on Boxing Day is enough for me. I love going out there and singing that national anthem and while the 100 has eluded me [at the MCG] ... my goal is just to get us off to a good start."
Warner said he expected captain Steve Smith to play despite being under an injury cloud.
