Under-pressure Australia opener Chris Rogers said on Sunday he cannot afford anymore batting failures or his test career will be over.
Rogers, 36, said he is feeling the heat to perform as potential replacement Phil Hughes is in the midst of a run-scoring spree in the domestic Sheffield Shield competition.
Hughes has scored a double-century and a century in recent Shield games as he pushes his claims for an Ashes recall.
Rogers said he realises more meagre returns such as the one and 16 he made in Australia's first test triumph against England will curtail his test career.
"I didn't contribute in the first game as much as I'd like to so it would be nice to get some runs in this game, for sure," he told reporters ahead of Thursday's second test in Adelaide.
"I want to be here the whole (five-test) series and score runs. That is my job, so I probably can't afford too many failures."
While most of his teammates rested after Australia's series-opening win, Rogers has been in the nets to prepare for the second test.
"I have probably hit the ball a bit better," Rogers said of his current form.
"I was able to do some good work this week and iron out a few flaws. Hopefully I can contribute this week."
Despite predictions of a docile Adelaide drop-in pitch for fast bowling, Rogers said Australia would continue its plans of unsettling England with short-pitched bowling.
"They probably haven't been challenged like that for a while," he said of the first test.
"And to have someone like Mitch (Johnson) bowling that fast is great for us.
"Perhaps they were a little bit rattled and we can use that for the rest of the series."
Rogers also expected sledging between the sides would continue, describing verbal clashes in the first test as "a lot of fun".
"It was good that we had the upper hand this time – they got into us in England, so it was probably due some going back to them," he said.
"But this is another game and they're going to come hard, so I expect some verbals from them.
"It may have been blown out of proportion a little bit. And I think England would understand it happens in a game, all is fair out there.
"We felt after England, it was a chance for us to say something back and that is what happened."
