Mushtaq Ahmed and Danish Kaneria both play county cricket regularly.

"I'm sure they will put us under a lot of pressure, but it's good to know that we've faced them before," said Vaughan.

"We have a good idea of what they're going to come up with, we've got a lot of footage and a lot of players have played against them."

He added: "It's not going to be the mystery factor that you sometimes get when you face someone like [Sri Lanka's Muttiah] Muralitharan because we've faced them so much in county cricket."

England are still unsure whether Pakistan will prepare spinning wickets, and field two spinners, or give extra help to their pace men.

Mushtaq, 35, has spent the last three seasons with Sussex and has not played a Test for two years.

But he has 185 wickets from 52 Tests and is taking part in a trial match ahead of the Test series, which starts in Multan on 12 October.

Kaneria caused England trouble in tour matches when they last visited Pakistan five years ago and made his debut during that series.

Still only 24 he has spent parts of the last two seasons playing for Essex and is likely to edge Mushtaq out if only one front-line spinner plays.

The tourists' first chance to acclimatise on the field of play comes in a three-day match in Rawalpindi, which begins on Monday.

"This is going to be a challenging series for us playing in different conditions," Vaughan continued.

"The players will have to make some technical changes to do well after their win at home."

"These are new conditions for a lot of our lads and they are excited about trying to do well in Pakistan, who have improved in the last year."
