Jos Buttler has insisted that he has no intention of changing his style for the demands of Test cricket.

The Lancashire wicketkeeper has made an impact with his unique approach to batting in limited-overs matches for England, and he believes that similar tactics will allow him to succeed in the longest format of the game.

"Of course I don't want to lose my one-day batting style completely," Buttler told reporters. "Around the world there are people who play in that aggressive manner and do well.

"When Kevin Pietersen played for England people were excited to watch him because he was always looking to score runs. David Warner has done that role for Australia very successfully too.

"It would be silly of me to go into my shell completely and curb all my natural instincts because that is what has got me to where I have."

Buttler will make his Test debut in the third Test against India in Southampton, which begins on Sunday.
