"Our bowlers stuck to their task, but I never thought we would get eight wickets so quickly," Inzamam said after his team whipped England by an innings and 100 runs to clinch the series 2-0.

England were in a position to save the match when they reached 201-2 at lunch before leg-spinner Danish Kaneria and fast bowler Shoaib Akhtar sparked a sensational collapse which saw the tourists lose eight wickets for just 47.

The tourists, trailing by 348 runs, were shot out for 248 in their second innings with Akhtar finishing with 5-71 and Kaneria with 4-52.

"Kaneria's two wickets opened the gates. His double-strike was the turning point of the match," said Inzamam.

England's slide began when Kaneria dismissed well-set Paul Collingwood (80) with his fourth ball after the lunch-break before accounting for Ashes stars Kevin Pietersen for one and Andrew Flintoff for duck.

Collingwood and Ian Bell (92) had sustained England's hopes of drawing the match with a 175-run stand for the third wicket.

"We bowled well before lunch but were unlucky not to get the wickets.

"At lunchtime we said we needed just one wicket. I knew if we'd take one or two it would be difficult for them to survive three hours," Inzamam said.

"After lunch Shoaib and Danish bowled very well, there was a lot of pressure on England and after we got the first wicket they came regularly.

"It was a tremendous effort from the boys, they really worked hard.

"Danish has been tremendous in the last two years and Shoaib's really serious about his cricket now and working really hard.

"But Mohammad Sami, Navedul Hasan and Shoaib Malik also worked hard on a slow track although they didn't get many wickets.

"To break the partnership was crucial and once Kaneria provided us the breakthrough we knew we were there."

The Pakistan captain, named man-of-the-series for scoring 431 in three Tests, said he was happy to lead from the front.

"I am happy I scored runs when the team needed them most. It is always satisfying when you lead from the front and I think this is one of the biggest wins of my career," he said.

This was Pakistan's first Test series win since beating New Zealand in January 2004.
