Both the 33-year-old Pietersen, who finished as the tourists' top scorer in the series despite managing just 294 runs at a rate of 29.40, and Flower did their best to rubbish the reports in bland public statements.
But it seems new England and Wales Cricket Board (ECB) managing director Paul Downton will have to decide if the talented shotmaker remains 'worth the trouble'.
"So adamant is Flower that the presence of Pietersen in the dressing room is detrimental to the future development of the side that he is believed to be prepared to resign his position should Downton, James Whitaker, the new national selector, and Alastair Cook -- if he retains the captaincy -- insist that Pietersen should be a part of that process," Selvey wrote.
There is also the question of whether Pietersen's chronic knee injury means his best days are now behind him, despite his stated desire to score 10,000 Test runs -- a goal which, if he reaches it, is likely to help, not hinder, England's prospects.
On a day when conventional 'bat for a draw' tactics simply led a to a flurry of wickets at the other end, Pietersen audaciously counter-attacked bowlers of the calibre of Glenn McGrath, Brett Lee and Shane Warne.
