Pallekele (AFP) - Pakistan captain Shahid Afridi admitted on Wednesday that calamity-hit wicketkeeper Kamran Akmal could be replaced behind the stumps by younger brother Umar at the ICC WC 2011. Kamran has come under fire from fans, media and a host of former players for his sloppy glovework which allowed Ross Taylor to escape on nought and eight to smash a breathtaking 131 in New Zealand's 110-run win on Tuesday. "Keeping with Umar is very much an option and we might try it in the next game (against Zimbabwe on Monday)," Afridi told GEO TV in Pakistan, of the same option which team used against South Africa in a one-dayer last year. He also defended Kamran's hard work. "If you see Kamran train, he puts in a lot of hard work. I don't know why luck deserted him. He is also upset about his performance and he realizes it too." Asked how "luck" seems to have deserted him so often in the last four years, Afridi smiled and said: "I can't give an exact answer to that. My job is to back him, to support him and hopefully he will do his best." Coach Waqar Younis also hinted that Kamran is on borrowed time, but that a decision on his future behind the stumps could be delayed until after the World Cup. "I think maybe after the World Cup we can think about it but now we are in the middle of the tournament and I don't think we can make such a change and panic. We should not." Kamran Akmal has endured a roller-coaster international career. He was first dropped in 2008 for the Asian Cup and again in 2010 when he missed five chances against Australia in Sydney. The 28-year-old also needed clearance from the Pakistan Cricket Board's integrity committee before being allowed to take part in the World Cup.
