Pakistan cricket coach Bob Woolmer [Images] says the International Cricket Council needs to take a re-look at the issue of 'doosra', which he described as a "new skill".

"I don't think it [doosra] is a throw. It's not a genuine throw. It's a new skill," Woomler said.

"The ICC [Images] have to look at whether they accept this new skill and to what level they are going to accept this new skill.

"Cricket is undergoing a metamorphic change. Bowling actions are changing because batsmen play spin so much better," he told reporters in Bangalore on Tuesday.

Woolmer said the 'doosra' was pioneered by Saqlain Mushtaq and other bowlers followed the suit. In order to bowl a doosra, one had to change the wrist specifically with an element of elbow in it, he said.

Asked if Pakistan will have a psychological advantage in case Harbhajan Singh [Images] does not bowl the 'doosra' in the third Test, Woolmer said out of the four wickets the Indian off-spinner took in the Kolkata Test, [all the] four were 'doosra'.

"It [if Harbhajan does not bowl doosra] might make a difference," Woolmer added.

Woolmer said the number of no-balls being bowled, especially by Mohammed Sami, is a worrying factor and added that he is working on it.

Asked if he is concerned about the excellent form of Rahul Dravid [Images] and Anil Kumble [Images], he said the visiting side would put up a 'front bowler' against Dravid [to contain him]. The batsmen would try to stop Kumble from taking wickets and score runs off him, he said.
