Clarke was part of the collapse and said he took the shattering defeat personally as he came to grips with the fact he could become the first Australian captain to oversee four test defeats in a series in England.
"I knew there had to be a statistic. I won't even think about it," he said.
"A lot of things are hard to swallow at the moment. I have taken losses personally especially when you make no runs yourself."
Phil Hughes appears likely to come in for The Oval, given he sits third on the tour run-scoring list behind Clarke and Chris Rogers.
Usman Khawaja and Steve Smith are the batsmen most under pressure, and will need something special in the two-day tour match at Northampton starting on Friday.
The series' averages list makes for ugly reading. Clarke and Rogers are the only two Australian batsmen to average in the 40s, and after that bowlers James Pattinson and Ashton Agar come in next.
However, Clarke stressed selectors must show faith.
"Everyone says rebuild, rebuild, rebuild. But you need guys in first-class cricket making runs to take someone's spot," said Clarke.
"You can't just drop someone if there is no one better to take their spot.
"We have to continue to show faith in young players in Australia."
Even after Rogers (49) and Warner (71) fell, Australia were well positioned at 2-168 with 131 left to win.
But after spinner Graeme Swann laid the groundwork, Tim Bresnan got the key wicket of Warner and then Broad ripped the heart out of Australia, inspiring a landslide that yielded 5-13 in 54 minutes.
Should Australia fail to win at The Oval they will drop to fifth on the ICC test rankings.
Rogers' maiden test hundred in the first innings and Ryan Harris' career-best figures of 7-117 in the second dig counted for nothing.
