Former Pakistan Test captain Shahid Afridi vowed to return to England on Sunday, saying the limited over series starting next month will be the launch pad for his ambitions to win the 2011 World Cup. The 30-year-old announced he would retire from Test cricket after the second and final Test against Australia at Leeds starting Wednesday, citing a lack of temperament for the five-day game. His announcement came minutes after he led Pakistan to a 150-run defeat against Australia in the first Test on Friday, where Afridi slogged 31 in the first innings and hold out for two in the second. However, Afridi - who led Pakistan to the 2009 World Twenty20 title - is determined to return for the subsequent limited over series against England. "I took a decision which I felt was right and now all my concentration is on the limited overs series against England which will be our first step towards winning next year's World Cup," Afridi said.
