KP's seeking swift return for England.
Pietersen yesterday agreed a central contract, initially for four months, with his return to the fold dependent on a "reintegration process" following the breakdown in his relations with Flower, dressingroom colleagues and his England and Wales Cricket Board employers.
At a joint press conference with ECB chairman Giles Clarke, Pietersen apologised to all parties for the "horrible" situation which has prevailed for the past two months.
Following his summer of contract wrangles and intrigue over "provocative" texts he sent to South Africa players during the Headingley Test, the 32-year-old was ex-communicated by England. Pietersen was dropped from the Lord's Test, picked in neither the squad for England's failed defence of their ICC World Twenty20 title nor the imminent trip to India - and not offered a central contract last month when all other senior players were.
He has made his goodwill clear, however, to play his part in his own rehabilitation - a mutual undertaking which will be overseen by Flower, with the help of a professional mediator if he sees fit.
The timetable for a successful process extends until the end of this year. But if it is to be completed so that Pietersen can be added to the squad to leave for India - via a training camp in Dubai - on October 25, swift progress must be made.
Asked if he believes that may be possible, Pietersen said: "I hope so. I want to play for England as soon as I can. The process has started really well and I believe, all being well, I'll be back in an England shirt as soon as possible.''
