England skipper Alastair Cook says it's his batting and not his captaincy which should be most under pressure this Ashes series.
Cook admitted the latest wave of scathing criticism from Shane Warne had raised his "blood pressure", but ultimately he was comfortable with a record of just one loss from 16 matches since being appointed skipper.
He was also unconcerned at being labelled unimaginative and negative as a captain by Warne as he prepared to return from a back complaint and lead England against Australia A in Hobart from Wednesday.
"I keep saying it, it's all about results," he said.
However, Cook said question marks over the England top order were legitimate heading into the first Test.
They were three wickets down for less than 65 on six occasions during the home Ashes in the winter, with Ryan Harris and Peter Siddle both managing early success.
England's poor record against the new ball could claim a victim for the Gabba Test, with Cook's opening partner Joe Root under pressure to avoid a demotion to No.6.
The Kookaburra balls used in Australia are known to swing for the first 15 overs and then settle down to allow batsmen to cash in.
England failed to post a total over 400 in the last series, heaping pressure on the top three.
"Especially with the Kookaburra ball it's a situation we can't allow to happen again," Cook said.
"Sometimes in England with overhead conditions that (early wickets) does happen.
"In Australia the bigger scores do happen and we know that is an area of major improvement we needed to do coming into the series."
England can certainly take confidence from the fact that Cook and No.3 batsman Jonathan Trott were the two highest run-scorers during their 3-1 triumph down under back in 2010-11.
Cook scored a double century in Brisbane and two big tons in Adelaide and Sydney.
"Any batter knows if you walk around a ground where you have scored runs in the past it gives you a better feeling," he said.
"The difference is that I'm now responsible for the team."
Root was another man on Warne's hit-list, with the Australian great claiming the rookie Yorkshireman would be "crucified" if he stayed opening.England have the option to open with Michael Carberry and move Root back to the middle-order, as he struggled in all but one innings - when he made 180 - in the last Ashes.
