Pietersen, who burst on to the international scene with a flurry of big scores in 2005, has failed to pass 50 in his last 17 one-day international innings for England, the last being back in November 2008 when he scored 111 not out as captain against India.
That has prompted some within in the game to question the long-term future of the South Africa-born star's place in the side.
Pietersen, 30, who was upstaged by man of the series Eoin Morgan in England's 3-2 win over Australia, was left out of the squad which beat Bangladesh 2-1 recently in order to rest and recover from a minor thigh injury.
Pietersen recently became a father for the first time and has enjoyed spending time with his family over the last 10 days. He has shrugged off suggestions that he will not be able to bounce back from his recent poor form.
He said: "I'm not worried about my form. It happens to every single player. It's difficult when you play all three forms of the game to just keep on going and going and going. I don't know if there's a big score for me around the corner. If it happens it happens. I'm not too fussed. I'm not losing any sleep over it."
England's Ashes win last summer, their ODI series victory, and May's ICC World Twenty20 triumph over the Australians have led to increased hope that Andrew Strauss's team will be able to retain the famous urn with victory Down Under this winter.
"I don't think that the one-day series win and the Twenty20 win will have any effect at all on the Ashes," said the Hampshire batsman.
"The only thing we can take out of those two series is that we know a bit more about their batsmen and bowlers and their fielding positions.
"The Australians are fantastic cricketers. They are tough human beings that will never, ever give up so it doesn't matter what the team is like."

Teaching your child to save
Pre-school (three - five years)
You can’t yet talk about investing or borrowing, but introduce a “classic” money bank and start putting gifts and allowances away. When the child wants a specific toy, have them save for it and help them track their progress.
Early childhood (six - eight years)
Replace the money bank with three jars labelled ‘saving’, ‘spending’ and ‘sharing’. Have the child divide their allowance into the three jars each week and explain their choices in splitting their pocket money. A guide could be 25 per cent saving, 50 per cent spending, 25 per cent for charity and gift-giving.
Middle childhood (nine - 11 years)
Open a bank savings account and help your child establish a budget and set a savings goal. Introduce the notion of ‘paying yourself first’ by putting away savings as soon as your allowance is paid.
Young teens (12 - 14 years)
Change your child’s allowance from weekly to monthly and help them pinpoint long-range goals such as a trip, so they can start longer-term saving and find new ways to increase their saving.
Teenage (15 - 18 years)
Discuss mutual expectations about university costs and identify what they can help fund and set goals. Don’t pay for everything, so they can experience the pride of contributing.
Young adulthood (19 - 22 years)
Discuss post-graduation plans and future life goals, quantify expenses such as first apartment, work wardrobe, holidays and help them continue to save towards these goals.
