Kevin Pietersen says he still has the desire to play for England despite recent poor form England's Kevin Pietersen walks back to the pavilion on the fourth day of their Ashes cricket test match against Australia, in Perth. DEFIANT England batsman Kevin Pietersen says he still has the desire to play for his country despite being disappointed with his form on tour. In a prickly media conference Tuesday, where he refused to go over comments by Graeme Swann that many believe were aimed at him, Pietersen acknowledged the team was "hurting" and he "felt like a clown" when out to a poor shot in Adelaide. But when pushed about his playing future, Pietersen said: "I'm 33 years of age. I'm batting as well as I've ever batted. I'll retire when I can't get up for England. I'm as good as gold. Pietersen said England had proved they were world class players and three poor results did not take that away. Kevin Pietersen bats during day four of the Third Ashes Test Match at the WACA in Perth. But deep down we're hurting as international sportsmen, as proud sportsmen ... We owe it to ourselves to turn it around. We've let a lot of people down, who have paid a lot of money to come and support us. He said he was giving no energy to the speculation around Swann's retirement, including comments from the players' grandmother claiming "nasty" Australians had forced Swann to retire. I only speak about what I know. I haven't heard of those [comments] and my interest levels in yesterday are less than zero," said Pietersen. I'm not giving any energy to what happened yesterday, the only energy I've got on this tour left in me is for Melbourne on the 26th.
