London - Controversy has been as much a part of Kevin Pietersen's career as linseed oil in an old bat, so the fact several British newspapers carried reports Wednesday of England coach Andy Flower issuing a 'he goes or I go' ultimatum came as no great surprise.
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'.
According to former England seamer Mike Selvey, the long-serving cricket correspondent of the Guardian, Flower's view was clear.Detrimental to the future development of the side'
"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.
Indeed Pietersen's maiden Test century has a claim to being England's most important of the 21st century so far, given that it secured the draw that saw England regain the Ashes in 2005 after a 19-year gap since their last series win over Australia..
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.
And in Mumbai in 2012 he made 186 against India on a spinners' pitch where most batsmen were struggling just to stay at the crease.
England's desire to have a captain across all three formats saw the lanky shotmaker given the job in 2008.
But a falling-out with coach Peter Moores -- not to mention his then assistant Flower -- meant Pietersen's tenure lasted barely five months before both men lost their posts.
Last year's Headingley Test against South Africa encapsulated Pietersen's England career.
Having produced a match-saving century where Dale Steyn and Morne Morkel were treated like club bowlers, Pietersen gave an equally stunning post-match press conference in which he proclaimed "it's tough being me in this dressing room".
The comments chimed with the idea of Pietersen the mercenary, after he clashed with England's management over his desire to play more often in the lucrative Twenty20 Indian Premier League.
Soon afterwards it emerged he'd sent "provocative" texts allegedly critical of then England captain Andrew Strauss to South African players. Pietersen was briefly dropped by England, only to be recalled when Cook took over following Strauss's retirement.
Roll on a few months, and Boycott was calling Pietersen "a mug" and all the top order "one-day clowns".
There is a case for saying a truly great batsman would, at least at some point, have found a way to steer a middle course.
But, as former England captain Mike Brearley once wrote, it's wishful to think a tortoise can ever jump like a gazelle.
And after the Sydney thrashing, Michael Vaughan -- the first England captain Pietersen played under -- said: "I hope England do not take the easy way out of this mess by making Kevin Pietersen the victim for the Ashes whitewash."
Speaking late last month, Pietersen put his own case: "Clearly I've made a few mistakes -- and that's been highlighted -- but I won't change the way I play for anybody because I think I've been pretty successful.
"You take the rough with the smooth. That is what happens."
Yet successive England teams have appeared to put as high a price on social conformity as actual playing ability.
"They don't want me but they want my runs," Boycott once remarked of his England career.
The same rueful 'epitaph' may yet apply to Pietersen too.
