England's new white-ball captain Jos Buttler has downplayed the prospect of becoming an opener for the England Test team after he was touted for the role by ex-Sri Lanka skipper Kumar Sangakkara.

Sangakkara this week said Buttler, who top-scored in the Indian Premier League (IPL) this season with 863 runs, could be a perfect fit for the Test team's newfound swashbuckling style under Ben Stokes and Brendon McCullum.

Sangakkara's suggestion was backed up by former England captain Michael Vaughan, who said he would love to see Buttler carry his form from the IPL into the longer format.

"I thought someone had written the wrong story, to be honest," Buttler, whose last test appearance came during England's disastrous Ashes defeat against Australia in January, told the BBC on Friday. "I don't think there is much merit in that.

"No, it's been fantastic to watch the test team over the last few weeks, so I've thoroughly enjoyed tuning in as a fan.

"It's been incredible to watch - you're gripped to your seat, aren't you? To see what they're doing has been brilliant. I've loved watching them and I hope it continues. There's no red ball in my bag at the minute."

Buttler will take charge of the England limited-overs side when it hosts India in three Twenty20 internationals from Thursday, followed by three one-day internationals.
