(REUTERS) - England batsman Kevin Pietersen has ruled out retirement in the wake of a 0-5 Ashes thrashing by Australia and wants to help regain the urn when they host the series next year.

The whitewash has led to calls by pundits for an overhaul of the England team.

Coach Andy Flower declined to confirm whether Pietersen, England's fourth-highest run scorer of all time and second in the lost series, was safe.

The South Africa-born batsman, however, said he had no plans to walk away.

"Very disappointed to lose 5-0, and not to score more runs personally. Tough tour against a top-class team," Pietersen, who scored 294 runs at an average of 29.40 during the five tests, wrote on his Twitter page.

Spinner Graeme Swann announced his retirement after the urn was lost following the third test.

Pietersen was one of several players who came under fire from former cricketers for his failure to dig in for the under-pressure team and shy away from his flamboyant, attacking style.
