Shoaib missed England's last trip to Pakistan in 2000

"The conditions are different," Shoaib told BBC Five Live.

"They'll find a different atmosphere, less bounce, good pitches for batting and it's going to be hard work for the fast bowlers."

"They're going to have to rely on the reverse swing to get people out. I think it's going to be a tough series."

England, buoyed by their 2-1 victory in the Ashes series against Australia, leave for Pakistan on 26 October, with the first Test in Multan beginning on 12 November.

Shaib hailed the England's performance over the summer but warned they still had plenty to learn.

"England are the best team right now," he added. "They have good guys around but Pakistan is different conditions," he added.

"There's a great opportunity for fast bowlers to learn off those kind of pitches."

Shoaib missed England's last tour of Pakistan five years ago, when England clinched the series with a famous third Test victory in Karachi.

But he has witness England's recent triumphs at close hands as he has been playing county cricket with Worcestershire.

And he believes a first-choice Pakistan attack, including himself, Mohammad Sami and Abdul Razzaq, could cause England's batting problems.

"We have the ability to swing the ball and destroy any team in a couple of spells," he added.

"Sami can swing the ball at 90mph, Razza can swing the ball, I can swing the ball. We work well as a unit."
