HAMBANTOTA (Agencies) - Pakistan coach Waqar Younis believes the recent spot-fixing scandal will not have a detrimental effect on their World Cup campaign which gets underway against Kenya today. Former Test captain Salman Butt and pacemen M Aamir and were banned on charges of corruption relating to last year's Lord's Test against England. All three also face criminal prosecution. But Waqar said his team, who will be in action for the first time since the bans were announced, are not worried about the past. "Whatever happened last year is now history." Pakistan are also eager to put behind them their tragedy-hit 2007 tournament. Four years ago, Pakistan suffered an embarrassing defeat at the hands of Ireland in Kingston and crashed out in the first round. As if the humiliation was not enough, their English coach Bob Woolmer died the very next day, threatening the World Cup and putting the players under investigation by the Jamaican police who initially treated the death as murder. Even after the death was declared as due to natural causes, Pakistani players came in for severe criticism from home fans who wanted them punished for their first round exit - their second in as many events. Younis and Misbah will be the key in providing a solid base for hard-hitters Afridi, Umar Akmal and Abdul Razzaq, who can run riot in the final overs and in the batting power play.
