Islamabad, June 3: Pakistan cricket team suffered a blow midway through their England tour with their bowling coach Daryl Foster deciding to quit accusing the bowlers of having an unscientific attitude.

"I don't want to sound critical, but they are very talented, and not scientific enough," Foster told Pakistan daily The News from Manchester.

Foster, who was hired by Pakistan Cricket Board for the England tour, said he would go back to Australia and would not stay for the triangular one-day series later this month with Australia as the third team.

"I would have liked to stay, but I cannot do it", he said.

Foster was earlier involved in a corrective stint with pace bowler Shoaib Akhtar, who was singled for throwing by New Zealand umpires recently, at university of Western Australia.

The success with Akhtar, subsequently cleared of chucking charges, paved his way for becoming a bowling coach for the Pakistani side.

Pakistan bowlers, especially Akhtar, failed to impress in the first test going down by an innings and nine runs. Akhtar claimed just one wicket although he did injure England captain Nasir Hussain which ruled him out for the second test, currently underway at Manchester.

Foster admitted he was not satisfied with the output of the Pakistan bowlers. "Even Shoaib Akhtar has still to work out his bowling action and also his physical fitness."

He said while Pakistan bowlers had "immense raw talent, in modern cricket it is just not talent which sees you through. I am not happy with the way they bowled in this series, to be honest. You can't get quality batsmen out by bowling on both sides of the wicket or too short.

"At this level and on such a pitch you have to be methodical in your approach; you bowl to one side of the wicket on a good length and dry out the runs and than wait for the batsman to commit mistakes", he said.

Foster said if Pakistan was to produce consistently good results it was imperative that the bowlers learnt to bowl scientifically and maintained their fitness.

"I think the PCB has to work on the scientific aspects of Pakistan cricket. They have to ensure that the young bowlers coming up learn from an early age how to combine their natural talent with application and methodical planning.

Foster denied joining the Sri Lankan cricket board on one-year contract from September this year. "This is the first time I have heard about this. I have been there a couple of times to help out with their cricket academy, but nothing more than that."

Foster said that he will be submitting a detailed report to the PCB after returning to Australia.
