ENGLAND skipper Alastair Cook admits to feeling less than 100pc as he contemplates a possible 5-0 Ashes drubbing but he could look to the experience of his opposite number for an object lesson in how quickly fortunes can turn around.
Michael Clarke has certainly plumbed greater depths in the three years since he first took charge of Australia in a test in the final encounter of the 2010-11 series at the Sydney Cricket Ground.
It has been England's turn to be battered physically and mentally in this series, though, and Cook will lead his side out tomorrow desperate to win the fifth test, avoid the dreaded series sweep and salvage a little pride.
"When you lose games of cricket, and you lose the way we have, it's a tough place to be as a captain," Cook said.
"It does affect people, make no mistake about it. It hurts for me, but it is what it is.
"For me to say I am 100 per cent right would be wrong.
"But I do know that I have a hell of a lot to learn as a player, as a captain, and I hope we can put in a good performance in this test match."
Clarke has been showered with plaudits for his captaincy in this series but has not forgotten that earlier this year he was pilloried when Australia were swept 4-0 in India and lost 3-0 in England.
