Lahore, Feb. 8 : Former Pakistan skipper Imran Khan has held President Asif Ali Zardari's interference into PCB's internal affairs responsible for damaging cricket in the country.

"Ad-hocism, the influence of departmental teams and the practice of the President being chief patron of the cricket board are the three major causes for our cricket problems," the Daily Times quoted Khan, as saying.

"Our domestic structure is still weak and one of the main reasons for our team's inconsistent performances. Unless we have only regional cricket and unless we end this ad-hocism in cricket nothing will improve," he added.

Khan expressed surprise at Pakistan's whitewash by what he called one of the weakest Australian team in years.

"This is one of the weakest Australian teams I have seen play, they are still recovering from the loss of some great players but they are surviving because of their strong domestic structure," Khan said.

Khan said the biggest problem affecting Pakistan cricket was a weak domestic structure.

"That is why we are not thriving despite having so much raw talent. We should have beaten this Australian team in the recent series," he said.
