According to the Sydney Morning Herald, the selectors hope to name an unchanged XI for the fourth Test in a row while England could make as many as three changes, but Lehmann is guarding against complacency as his team seeks to extend its series lead.
Lehmann said that Australia's top order needs to make some more runs and one of the big things is making them in the first innings.
Meanwhile, opening batsman Chris Rogers, who combined with David Warner for an opening stand of 150 in the second innings in Perth, has said he feels under pressure to shore up his position, as one of two top-seven batsmen who have not reached triple figures so far, the report added.
Lehmann also said the harmonious atmosphere in his own dressing room was no different when the team was losing in England, even if it is perceived differently at 3-0 up, the report mentioned.
