Former England captain Kevin Pietersen says he would be interested in joining the team’s coaching set-up and ​would look to alter their approach to test ‌cricket. England’s 4-1 Ashes defeat in Australia triggered a January review by the England and Wales Cricket Board, putting scrutiny on coach Brendon ​McCullum’s aggressive “Bazball” tactics. “I would absolutely look at it ​in the longest form of the game and ⁠try to help these guys understand that there is ​a way that you can play,” Pietersen, 45, told ​The Guardian. “Tactically, you’ve got to understand the situation. I know I’ve got all the credentials. I know I do. I’ve worn every ​single T-shirt.“ The former Ashes and T20 World Cup winner ​said England needed a more measured approach in Tests. “In the shortest ‌form ⁠of the game, sure, play without fear, go out there, be brave, be reckless, be careless, be whatever you want. In test match cricket, you cannot do that,“ ​he said. “I ​hit back at ⁠the stumps for a long time in my career. I didn’t run down the ​wicket against Australia’s fastest bowlers and try ​and ⁠slog them for six first ball. I knew my limitations.” England, who were eliminated from the T20 World Cup on ⁠Thursday after ​a seven-wicket loss to India, ​next host New Zealand in a three-match test series in June.
