Pakistan enjoy an unassailable 2-0 lead over the English.

"I think Pakistan will complete a clean sweep in the third Test. They can whitewash England," Afridi told reporters at a function to launch the autobiography of former chief selector Salahuddin Ahmed.

Afridi said Pakistan enjoyed a psychological hold over the English batsmen.

"I see this series as the best opportunity for Pakistan to win the series 3-0. As they keep on winning they are getting hungrier for success and that is always the first sign of a team turning into a top class side," he said.

"Another good thing is that all the players realise their responsibility and are contributing and supporting each other on the field."

The all-rounder, who will join the team for the one-day and Twenty20 matches against England from next week, said Pakistani players have made winning a habit.

"After winning the first two Tests, the morale and confidence in the team is very high," he added.

Afridi, who was captain of the one-day side until last May, said that the way Pakistan are improving, they could soon match the feats of other great teams.
